645840 - title bar black & buttons gone after changing windows 7 theme

Status: RESOLVED DUPLICATE of bug 656891

(Firefox :: General, defect)

Description

[Narek K.]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0

The non-maximized window title bar is all black and the minimize/maximize/close buttons are GONE -- this happened after I switched from "Classic" windows theme to "Aero" 

Reproducible: Always

Steps to Reproduce:
1. Set Windows 7 theme to classic (non-Aero)
2. Open Firefox, maximize it and leave it maximized.
3. Change Windows 7 theme to Aero (new default theme)
4. Go to Firefox and double-click title bar to return to normal view (non-maximized)
Actual Results:  
The title bar is black, the maximize/minimize/close buttons are not there (clicking in their normal location produces no action either).

Expected Results:  
It should have changed the Firefox theme along with the rest of the Windows environment.

Works fine for me. Please post the graphic section from about:support 
After that disable the the hardware acceleration under
tools/options/advanced/general and retry it.

I just encountered this problem as well, and disabling hardware acceleration did not help. And I think I know why you couldn't reproduce it as well, since I couldn't immediately.  After switching from Aero to Classic, you need to restore down, then maximise fx, then change back to Aero.  With that step the problem occurs with and without h/w accel, without it it doesn't appear on either.
Additionally the title bar seems to be completely transparent in maximised, and creating a new fx window will only partially fix the problem: The titlebar will be of correct color/transparency and the window buttons will be back, but the tab list and tab close button (if you have it at end rather than on tabs) will be visually above the window buttons, but interactively behind.  If you require any screenshots of the problems, or anything else, just let me know.

Similar thing appeared when log in at real console after using Remote Desktop. When resizing native windows title bar blinked and overlayed by black window.

Attachment: Black title bar

Attachment: Non-black title bar

After pressing "Browse..." button on attachment page title bar was redrawed by native windows elements. Minimize/Maximize/Close buttons shown, but not functioning.

Resizing window shows black title bar again.

I've had these two sets of steps to reproduce sitting in a text file for a while.  The problem was as soon as I'd seemed to create one that worked consistently, it stopped doing so :S Putting them here so they may be of use and so I can finally junk the text file.

After some more experimentation the steps to reproduce are actually a little simpler:
1. Have a maximised fx window in Aero theme
2. Change to Windows Classic theme
3. Restore down the fx window
4. Change back to Aero theme

Here are the results of different permutations of actions:

Maximised->Classic->Restored->Aero=Problems as described
Maximised->Classic->Restored->Maximised->Aero="
Restored->Classic->Maximised->Aero=Misaligned tab buttons, fixed by resize
Restored->Classic->Maximised->Restored->Aero=No problems


New repro:
1. Maximise Firefox
2. Change to Windows Classic theme
3. Restore Firefox
4. Double click titlebar to maximise Firefox
5. Change back to Aero theme
6. Window buttons will eppear slightly dodgy, restore down to see full problems
