Flash player freezes in fullscreen mode

Question

A lot of users on one of our online apps complain about the app freezing
in the fullscreen mode.
I googled and came across many others complaining about this problem for
other flash apps.
Is it such a common problem,
or are there known causes for it?

Answer 1

This is a problem with GPU acceleration on some video cards. Have affected users turn off Flash hardware acceleration.

1. Go to any website with Flash (ex., photoshop.com)
2. Right-click on the Flash movie
3. Click Settings...
4. Select the "Display" tab if it's not already selected (first tab)
5. Uncheck "Enable hardware acceleration"
