Fix for Firefox flashing when in full screen 2
Since Jaunty, when Firefox is displayed in full screen (F11), any of the following actions will result in Firefox disappearing for a second and the background desktop image replacing it:
- right click
- alt-tab
- hovering over a link with a tool tip
That happens if compiz is in use and I verified the problem both on machines using Intel and Nvidia video cards.
The fix is easy:
- go to System -> Preferences -> CompizConfig Settings Manager -> General
- uncheck "Unredirect Fullscreen Windows"

finally, i thought it was due to one of the desktop plugins, silly. thank you.
I'm using KDE 4.3, I don't think it uses Compiz, do you know what the equivalent fix might be? Thanks.
