corrupt gui when switching from fullscreen program
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20140913030206 Steps to reproduce: 1. Have Nightly open and as active window 2. Click on a fullscreen program in taskbar which is already running 3. Press windows key to get out of the fullscreen program. Actual results: Nightly GUI becomes completely corrupt and browser must be restarted. It only happens with Nightly, no other browser or program experiences the same thing. Also tried an old install of FF 26.0 and it is ok. See screen capture: https://www.youtube.com/watch?v=tQwDC0bwhmw Expected results: Nightly should display correctly.

Does it work if you disable the hardware acceleration under (alt key)/tools/options/advanced/general:/Use Hardware acceleration when available (Firefox restart required AFAIK)
Disabling hw acceleration makes it work. To be honest.. unless someone has irresistible urge to debug old AMD drivers better close this bug and spend your time in some better way. I will try to switch to an older driver or something.
I'm only a bug triager and do not decide what or if the developers will do something. We can blacklist your graphic card driver in Firefox as example and all users with this driver will not have the problem without looking for a solution for their problem and finding the hardware acceleration switch in the options.
