I think you need 2 or more windows to trigger the bug. I cannot reproduce it with a single window.

I realised that it can be reproduced in a single window if you repeatedly change theme from Windows aero to windows classic. and further more if when the bug occur, if you open a new window, the panorama button is at the wrong position(but other error of the bug is not present).

Is this a duplicate of bug 607251? Is it still a problem in latest nightly builds or Firefox 4 beta 10?

It was a little difficult to provoke the bug this time (some open windows and about 20 theme changes), but it still happens.

As AndreiD specified in bug 635896, this issue occurs when the option "Use hardware acceleration when available" is checked -> hardware acceleration problem.

I've to say, that exactly happens to me, BUT, not when I change between Classic/Aero... 

It happens only when I've this program open in parallel with Firefox...

At the begining, when I hover on Windows Caption Button while in Aero Mode, I can see the over those button, the Classic's theme too... 

Check some screenshots...

This while I'm with Aero Theme: http://k.min.us/jjNwQy.png

I hope it will help you... I've a personal "userChrome" but as I can see, additional people have the problem too. The program isn't windows native designed. Maybe it helps too.

Is this the same issue as in bug as 607251? 
Considering duping this one since that one is already set on New.
