Im having problems with the crop tool (r).  No gridlines to help straigthen and a blue screen with a white cross may appear.  Suggestions for change that?

When I first downloaded and used LIghtroom testing, it was fine.  Now, when you press 'R' guidelines usual third are not displayed.  When you want to straighten a picture usually find the grid lines, but now they do not have.

Also, after using the tool of R twice more high on most of the images, it changes just a blue screen with white triangles on it and then I can not crop or straighten anything.  Very strange.

I used Lightroom for many years, but it's strange and I can't change it back.  I watched all I can think about and I don't know why he changed.

Any help would be welcome.  It is testing at the moment and I won't buy it until I can work on what's happened.

Thank you, Karen

Disable the GPU acceleration.

For Windows, you should go to the website of the manufacturer of your graphics processor and check the driver updates. Once updated you can try turning on GPU acceleration, otherwise leave this option disabled.

Mac GPU, updates occur with updates to the OS.
