Scrolling stutters

All of a sudden, when I scroll with my trackball, the window that I am scrolling in stutters terribly. I went in nets of old who spoke on this subject and reset the PRAM, AutoCad, I opened, I changed the settings of the trackball, I rebuilt my preferences, nothing seems to fix. I have also connected to a guest account and does it as well.

Any ideas?

Make sure you have at least a complete external backup.   Hardware issues can cause this kind of oddities.   Try another device - some other wired mouse or a trackpad with or without wire or such - and test the scroll and see if the problems are specific to the Mac or the trackball.   If that does not show the problem, remove all the external USB devices, with the exception of the trackball - no hubs, no disk, just the trackball and (if you use a wired USB keyboard) the USB keyboard.    If that all fails... so take a look for the blocks of the errors using the Console.app (Applications > utilities).   If you decide to display data from newspaper here, please not after more than a block of all blocks of repeat messages, please post no more than a hundred lines, or if the total log data and please review the detachment seeks not something that might be confidential.

    After updating to Mac OS and safari 10, I noticed that when scrolling the page animation stutters when slowing down. It is not consistent, but it seems quite often. I can't do with extensions, after you disable Adblock (the only extension I was using) still stuttering. It is more pronounced when scrolling to the top of the bottom of the page, at average speed.

  • Jump in the middle of an audio track streaming on various sites causes the stuttering and audio glitch

    Hello

    Please refer to this thread for support on the technical support of SoundCloud forums. The thread contains all relevant information, including videos of the screenshots problem and console, made by myself and others. https://www.soundcloudcommunity.com/SoundCloud/topics/skipping-to-the-middle-of-a-track-causes-stuttering-and-glitchy-audio-chrome-Firefox

    In short, when you try to move forward for streaming audio, there is a memory buffer/stuttering problem that prevents a correct reading of the track. This problem is confirmed on SoundCloud and Traxsource and other people in the support thread mentioned Mixcloud and other streaming sites. In other words, it is not the special streaming service fault or another.

    The problem does not occur in Microsoft Edge, Internet Explorer or Chrome. Well, to clarify, when the issue was published on SoundCloud support forums, Chrome was having the same problem. However, they made a version a few days ago thrust, that fixed it.

    Here's my original on the SoundCloud support post (less), which has the relevant details. Note that we have updated both Flash and Firefox recently, so although I have mentioned earlier in my original post, everyone involved has since updated their browsers and Flash.

    From now on, the only solution for the problem is to go back to Firefox 40.0.2. Thanks for any help =)

    Original message =.

    Jump in the middle of a track causes the stuttering and audio glitch (Firefox).

    I am running Windows 10 Pro.

    There seems to be a problem of caching that affect reading - I started noticing this problem three or four days ago. Previously, I could jump through my feeds at will, go straight until the middle of the tracks or mixes of listen seconds and determine if I liked the track. Now, I can't do it on Firefox 41.0.1. The problem is simply annoying on songs that are 3 or 4 minutes in length, as I must leave "cache" maybe ten seconds before jumping. Unfortunately, the problem is a game-breaker on mixtures which, for example, are 90 minutes long. If I jump to a point directly in the middle of the combination, nothing happens. The play button alternates between the 'Play' symbol and the symbol of 'Caching' ('... "), and so audio resumes, it is glitchy and consists of different parts of the track being played at the same time.

    I've eliminated my internet connection as the source of the problem by loading on board. On the edge of 20.10240.16384, the problem does not exist. I can scroll down to any mix of 2 hours in my stream, click on the middle of it, and the audio starts right up. No caching, without stuttering or glitching.

    I drove back Flash version 18 to see if it solved the problem in Firefox, but it did not. The problem persisted, so I re-updated to Flash 19.

    Yes, I understand how all versions and updates to work. I meant it as a generation of powder magazine. My bad.

    I consider this problem to be solved. Several different pre-release versions of Firefox have solved the problem; I have personally used both of them that work perfectly. A representative of Bugzilla stated that the patch will be integrated into Firefox 42, which will be released on 3 November.

  • Firefox hangs for a short second while scrolling.

    Very well. I will do my best to explain this and the steps I tried in vain to resolve the issue.

    Normal use (even without any addons at all) after a short time, 5-10 minutes, sometimes faster my Firefox stutters for a second, my mouse stops during stuttering and then it thaws. Once that starts happening, it happens VERY frequently, like all the other seconds, when I scroll to the top and to the bottom of a page is when it is more sensitive, the mouse cursor stops while firefox is 'frozen' and he returned after a short second.

    I tried many things: I completely deleted firefox to my system, most of the registry entries, all linked files, deleted and I tried a fresh install again. That seemed to help for a second, but after a few minutes of browsing the symptoms return.

    I have concluded that it is not addon for, as I began cool and does not have everything on my last attempt to reboot, that she was having the same problem with or without addons

    I have tried this fix sessionstore.js, increasing the interval, disable it completely, that doesn't seem to help either.

    This does not happen on Chrome, is that firefox does it. It is not even a serious if it's a website, if I scroll to the top and down on the troubleshooting page in firefox it stutters even while scrolling.

    I tried everything I know to do, and I can't fix it myself. Please, if you can help I would appreciate it.

    I solved this problem. The problem was my Ipod is connected to the computer. Whenever the ipod is plugged in, firefox stuttered and offbeat as indicated. I noticed when I got my ipod disconnected for a while to use another usb device, firefox has been resolved, I thought it was the update of this week to be fixed. Couple of days later, I plugged my Ipod in, the problem returned. But, since I started to load my ipod Besides, the problem disappeared. Thus, someone at - it still have this problem, check to see if you have an ipod, an iphone or another usb storage device is connected.

  • HP Pavilion HauppaugeWinTV HVR 1290 and Windows 7 - Audio stuttering problem

    Hi all

    I have the WinTV HVR 1290 card installed in a new building.  Window7 Media Center does a great job, support the DVR functions.

    I searched for the latest drivers that HP has on Windows7/64 Bit support.  The current problem is that the recovery of a sleep almost always ends with an Audio stuttering problem.  A reboot clears the stuttering.

    HP probably has some drivers of Windows7 pre-release for sold third party hardware integrated into the Media Center PC.

    Any help would be appreciated.

    Thank you

  • Toshiba 40RV753 - stuttering TNT HD

    Hello

    I have a problem with my Toshiba 40RV753 and stuttering watching TNT HD. I first noticed what is happening to all about November 2014. I replaced my original antenna, cable connections and who has not solved the problem.

    Issuer = Winter Hill, North West, England.
    Distance = approximately 5 miles, line view.
    Aerial is Vision V10 - 36L periodic journal.
    Cable is 15 meters Webro WF100.
    Toshiba 40RV753, applied new firmware 10.2.63.5 release.

    The stuttering occurs frequently watching TNT HD using the 40RV753 of Toshiba, built in tuner. I tested it with treatment and image color, resolution + power options. Stuttering is even more evident during the movement containing, or scrolling panoramic scenes.

    I didn't notice any stuttering watching TNT SD using the 40RV753 of Toshiba, built in tuner.

    I have not noticed any stuttering while using the Toshiba 40RV753 a HDMI input from my PC, works of HDMI input perfectly with no stutter.

    I have not noticed any stuttering while using the same antenna and cable connected to a PCTV, Freeview HD tuner works perfectly with no stutter.

    My neighbors that Panasonic TV works perfectly when connected to my antenna.

    My Toshiba 40RV753 suffers from stuttering when it is connected to my air neighbors.

    (De) Fortunately I have two Toshiba 40RV753 and the problem occurs on two televisions.

    Someone at - it ideas?

    Hello

    Try to reset the TV by default and to retune the tuner of channels especially the HD.
    To be honest that's all what you do...

    I m not very well why the DTT channels cannot be received correctly, but from my point of view of a few weak signals could cause this problem.

    Google for TNT choppy HD picture and you will get many hits. It seems that more people have issues similar receipt TNT

  • IDT HD Audio stuttering apps/games/tf2 3d - Windows 7 x 64 - Pavilion dv7-4113tx

    According to the rules, I have need of the State:

    I am an employee of HP, my views/opinions/etc are mine and do not reflect those of HP.

    I filed a bug report kind - but I don't know where to start, I do not work in an area that has nothing to do with the manufacture of products from HP; It is my free time now and I do not have intranet access .

    I recently got a HP Pavilion dv7-4113tx Entertainment Notebook PC [XV780PA] for my personal use, and overall, it was very good. It comes with windows 7 Home Premium x 64 bit.

    There is however a problem I have to implement what concerns games, or I guess any application intensive 3d, especially Valve games, my criterion of choice is Team Fortress 2. Edit: another game that stuttered, but less frequently - Serious Sam HD.

    The game works perfectly in native resolution (ed: change the lower resolution will not affect the bug)-I'm moving 100-120fps but about every 30 seconds - 2 minutes, there is an audio/video stutter (stuttering, she repeats the dernieres.5 seconds of audio about 3 - 4 times in a loop while the screen freezes on where begins the first audio stuttering) which will make the game of 'freeze' for about 2 seconds and then continue where you left off.

    Team fortress 2 is an incredible critical moment online multiplayer game, and this delay essentially means my e-death several times.

    I thought at first that it was the graphics card or drivers - I put drivers at latest on the ATI site, which has increased my fps, but the stuttering was always there. After searching around on the internet a bit, I found a suggestion to turn off the audio driver (like - Device Manager lists IDT High Definition Audio CODEC) as test - so I did.

    The game purrs like a kitten - absolutely no stuttering. my score went up immediately

    So, my next step was to try to get updated for the IDT Audio device drivers (note, I can't find a name of model anywhere in the features of hp - or on the internet really) - I've discovered IDT themselves cannot release the pilots, that these can be obtained through OEM.

    which brings me here.

    now - closest to the drivers, I found I needed here: Driver Audio IDT high definition (HD) for Microsoft Windows 7

    Note: - it says on the page that they are 32-bit drivers - but I found that they work with the 64 bit version of windows.

    These worked a little better - he fixed another problem - by the way if you use volume controls in an application full screen which she will spend on the desktop to display the scroll bar on screen volume down (what was probably redundant because windows 7 displays the volume of the speaker in the lower right corner)- and he turns just the audio down as expected.

    However - the stuttering is still very much present .

    Then, I tried to use the wizard to Support HP to run automated diagnostics and troubleshoot... which then downloaded the old drivers who gave me this issue of full volume control screen back again once - so I guess that the original drivers.

    So I installed the other drivers again.

    My next test will be to use an external USB sound card to see if that will allow me have games with sound.

    An agent appropriate at HP can you please address this concern and notify when this bug - IDT says they work with OEMS to solve problems on a regular basis on the IDT link above.

    In my view, that it is a question that will probably require a bug fix.

    EDIT: I will cross-post this to the game as well.

    second edition: added serious sam, res fullscreen downgrade info, reference removed firewire firewire no!

    Got a solution as possible here. Without changing the HARD drive (for me problem was there).

  • Audio stuttering then crash by watching the video with Windows Media center

    I'm having a problem with Windows Media Center which seems to have left me speechless. Whenever I have try and watch live TV or recorded using Media Center program, he starts to play to repeat the first second of audio for about 6 seconds and then stops playing gives me an video error and won't let watch me something else. I have a Setup Xbox 360 as an Extender and having no problem whatsoever. The strange thing is that, if I open the program saved directly from Explorer windows with media center, it will play well. If I stop and try and then click RESUME He stutters and gives me this video error.
    It used to work fine until I started to play with the audio settings from 5.1 to 7.1 audio in the windows configuration settings. I changed the settings in-game your 7.1 speakers. Actually I tried to switch back, but when I try to 'Test' the speakers it gives a sound like it is stuttering and I still get the video error when I try to play. Any help would be greatly appreciated.

    Audio problems in Windows Media Center

    update the following drivers: -.

    Audio driver

    Graphics card driver

    Driver card TV Tuner

    You may need to reset if necessary WMC.

    Run the Setup again.

    Open WMC > tasks > settings > General > installation Windows Media Center > rerun the installation

    Does that help?

    If the above does not help then try to reset WMC: -.

    Open Control Panel > uninstall a program > turn Windows features on or off > scroll multimedia features > uncheck the box against Windows Media Center > follow the instructions on the screen > Reboot > open again to turn Windows features on or off in the control panel > scroll multimedia features > check the box against Windows Media Center.

    Now reconfigure WMC again.

    You can also go for a System Restore-select any restore point when it did not have this problem.

    I just bought a new Intuos Wacom Pro 5 and I am trying to configure shortcuts so that my workflow will be more effective, but when I put my stylus to pan/scroll and use it in Photoshop CC 2015, it lag/stutters a little. When I manually select the hand tool (which is supposed to do the exact same thing as the command on my pen) and use in Photoshop it does lag at all. Everyone knows about this problem?

  • Audio stuttering on MBPro Sierra

    I'm on a MacBook Pro installed macOS 10.12 retina end 2013 (Sierra).  For several years, I have used a bluetooth JBL of Charge 2 for this portable audio speaker (and sometimes my iPhone and other iPhones).  He has always worked flawlessly.

    Today when I hit play on the audio iTunes began badly stuttering.  After several searches, advice and read everything that I could find (especially regarding similar issues on other versions of the operating system as El Cap, Yosemite, etc.), I did the following, without result:

    • Not matched and repaired the speaker

    • Restarted/rebooted both the speaker and the MBP

    • Reset NVRAM and SMC

    • Redownloaded and reinstalled Sierra

    • Reset NVRAM memory new

    The problem persists.

    Note: I have also been hang this portable projectors in the classroom for several years via a port mini display to VGA and have never had a problem.  Since the upgrade to Sierra, can I talk to is no longer in the spotlight (my MBP always spoke to my external monitors (via the adapter, even) but not the spotlight.  I wonder if these issues are linked, at least to the extent where they came after the upgrade to Sierra.  Thanks in advance for any thoughts.

    Moments after the announcement of this question, I went into my list of connection and uninstalled Knock, an application that allows to unlock the lock screen by knocking on an iPhone.  And here, the sound works fine now.

    I guess I should have posted earlier, because I found the solution immediately after.  At least the bluetooth problem is now solved!
