Attachment: firefoxTestDualScreenHeaderMissingWin81.png

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0 (Beta/Release)
Build ID: 20140520004002

Steps to reproduce:

Firefox Aurora :: 31.0a2 (2014-05-20)
1) Setup computer with windows 8.1 and 2 screens attached and extend your desktop
2) Open firefox and move window to secondary screen (right screen)
3) Resize the window manualy by draging the corners or go to full screen
4) Issue has now occured
5) By moving window back to primary screen (left screen) + resize window
6) Firefox is now back to normal


Actual results:

The header of the window goes white/gray.
Header = address bar, bookmarks, tabs +++
The rest of firefox is working fine.

Header of firefox goes invisible/white or "unreadable"

See attached picture for my 4 test and results
1: Issue occured unfocused window after resizing (Secondary screen)
2: Issue occrued focused window after resizing (Secondary screen)
3: Normal behavior unfocused window after resizing (primary screen)
4: Normal behavior focused window after resizing (primary screen)



Expected results:

That firefox can be resized in secondary screen without "missing" the header

I wasn't able to duplicate this issue in 31.0a2 but I may be missing something from your steps to reproduce.

I tried this in Windows 8.1 with two screens, moved the Firefox window to the secondary screen, then maximized the Firefox window. Its headers appeared normal.

Hi Liz,
I tested it again on my setup and the issue still occurs: (31.0a2 (2014-06-09))

Make sure the left screen is primary, and right is secondary, and then reboot your computer before you do the test.

We have tried to reproduce this issue on both Windows 8.1 x32 and Windows 8.1 x64 on the Aurora build from 2014-05-20 and on the latest Nightly( build id: 20140706030226)without success.

Can you please try reproducing it using a new profile and safe mode?
If you still reproduce it like that then please provide us the graphics information from about:support page.
