reduction of severe frame rate when you touch the screen, iOS

Hello
I have a simple app with scroll to the top of the stage with a bitmap image in each of the clips of 2000. They are moving incredibly fast at 60 fps.
But the moment that I even put a finger on the screen the fps drops to about 40 if I move my finger it drops to 30 fps.

is this a normal behavior?

There is no listener of events or something like that.

Thank you :-)

I did a couple of things that have improved the framerate:

mouseEnabled = false;

mouseChildren = false;

No movieclips, only bitmaps, perhaps of sprites.

If you use clips for controls, make sure that they are not nested in a different movieclip that covers the entire screen. (avoid nesting where possible)

  • Satellite M30X powers off the power when you touch the USB port

    Hello everyone, just registered and it is the first problem:
    As there is no general hardware forum, I post my problem here.

    I got it twice, my laptop
    (Product: Satellite M30X, Version: PSA72E - 008010GR) just went completely off.

    Motherboard:

    NorthBridge: Intel i855GME
    SouthBridge: (ICH4-M) of 82801DBM LPC Interface Bridge
    Motherboard model: Toshiba EAL20

    USB:

    82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI controller #1-3
    Version: 1.0
    Interface: UHCI
    Frequency: 48 MHz

    82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB 2.0 EHCI controller
    Version: 2.0
    Interface: EHCI

    I have the latest Intel Chipset drivers installed and Windows XP Home SP3 with all updates.

    Once when I hit just the back USB ports with a USB plug, the other time when I unplugged my bluetooth key (climbing din't remove it).
    There was no blue screen or message of any kind, not even in the registry after you start the system again or this fatal system error box when you start after a system error.

    Just a total failure. But it works fine the rest of the time. I also tried to remake the script, but it didn't work.
    I have cleaned with a vacuum cleaner to remove dust and has taken a good look, but saw no difference to the side track.
    Maybe the clamps of the wand to shield a little more out to the contact pins on the rear.

    What bothers me a bit, it's some time ago, I had the laptop one computer my knees and I forgot that a memory stick has been connected to the rear. The stick was pushed up and was slightly damaged.
    Still works well. Now for me, that I broke the USB port Insider somehing.
    I could not determine also the loose parts or unfirm at all.

    Y at - it there, diagnostic software that measures the motto of the port or power problems?
    I have a multimeter, fetch short-circuits with it?

    I saw a package of drivers Intel for USB 2.0 over there, but I can't find it on their page, advice?

    Thank you very much for your help, I just wanted to update my RAM and now I am not so shure if my laptop will last the next week.

    Hello

    I put t know any diagnostic software that could analyze this question, I think that a technician of the ASP may be able to provide exactly this question results

    > What bothers me a little is that some time ago, I had the laptop and my knees and I forgot that a memory stick has been connected to the rear. The stick was pushed up and was slightly damaged.

    I think this might be the reason why the laptop stopped while you touch the USB port eventually ports were damaged by using the memory stick, this could cause the laptop off

    However, what we can do is to provide some suggestions and assumptions
    It you want to know why this is happening exactly, then you need to contact a technician laptop for a control.

  • Text and images disappear in overlays frame scrolling when you turn the iPad

    I'm having this problem:

    When I rotate from portrait to the horizontal, content scrolling frame iPad disappears, the same phenomenon occurs if the first view is horizontal to vertical.

    The names of levels of different content and images are different.

    The problem comes with the app Adobe Content Viewer of an iPad 3.2.1 version 3 with iOS beta 7 v.6 so that this does not happen on an iPad 1 with iOS 5.5.1 the file downloaded to the producer Folio folio is the same.

    Suggestions to solve this problem?

    Below is a short video showing the scrolling image, text and images disappear in two articles (but this happens in all pages)

    A fix for a nearly identical issue was released on 13 September. Did you rebuild the application and try again?

  • CC of Photoshop do not stick frames properly when you use the animation timeline.

    Someone had this problem where they want to copy and paste a picture or a picture on a previous one on the timeline art and it creates a new layer not video instead? It seems to me that after working with the file for some time. There is a logic to what I'm missing?

    I'm working on an animation "straight ahead" and need to juggle the frames around the calendar, and he won't let me paste it into my video layers. It just does not allow me to do. Others in my animation team have done this experience as well.

    I tried the customer and that they did not understand what I was describing.

    ANSWER: (From Brett)

    The problem is that you can not stick in a video layer framework that already has a kind of content inside. So, if you have already of this drawing on a given frame of a video layer, and then you try to stick in this layer, it will stick in a new layer instead. If this framework has no content yet or you clear the existing content, you can paste into this framework. If you come across a situation in which you cannot stick in the frame, you can select and delete the content, then paste will work.

    Brett has solved! I hope that Adobe treats this confusion between the restriction in the future, if there are workarounds.

    Many thanks, Brett!

    Hello

    There may be something wrong with the screen of laptop computers.
    I guess that the graphics card is ok because the external screen works properly.

    But it s very interesting to know if you are using the graphics driver from Toshiba. If this isn't the case, please check if this problem also appears after installation of the graphics driver from the Toshiba driver page.

  • Satellite L50-B-1NM - speakers turned off when you move the screen

    Hello

    yesterday, I got Toshiba L50-B-1NM.
    Everything seems to be ok except for one thing.
    Speakers to stop when the screen is slightly moved. There are positions of the screen, when they work, but just slightly push the screen and they are now closed. Movement of the screen has no impact on its external [helmet], is without a doubt the speakers or its connection.
    I wanted to use warranty, however, I am not sure if it covers this kind of defective. Anyone know?

    And he also said: [even if the warranty is still on]
    Product not available, unfortunately your product is currently not available so please contact your place of purchase.

  • Why Photoshop stop when I touch the touchscreen on the lap top and I can avoid it?

    Every time I start Photoshop you stop with this message below saying that it has stopped working. I realized that it stops when I touch the screen. How can I avoid this and it is possible to work in Photoshop using the touchscreen?

    It is not normal that photoshop to complete when you touch the screen. Either something with photoshop is corrupt or the driver for the touch screen.

    First thing to try is reset the photoshop preferences. CTRL-k on windows or cmd - k on a mac, and at the bottom of the Panel is a button to reset the preferences.

    If this does not work, uninstall photoshop, restart your computer, reinstall photoshop.

    Next is to see if you can update the driver of the touch screen. Sorry I don't know how to do and would depend on if your windows or mac and what version of the operating system that you use.

    Finally run CC Cleaner

    This will remove all traces of Adobe programs on your computer. Restart the computer, and then reinstall the Manager then photoshop.

    I hope that one of the above will solve your problem, if not let us know.

  • Posterize time VS Preseve Frame Rate when nested

    Hello everyone.

    When nesting two Compositions with different frame rates, I heard That Posteriser times, is a former effect that many people use it.  But it can cause a lot of problems.

    So it's better inside Composition advanced settings: Check preserve the frame rate when nested or in queue ?

    Thank you.

    If you need to keep the pace, I would choose just preserve the cadence. However, there are many times when you do not even need to preserve the cadence. So, if you don't actually have to preserve, not.
