Status: RESOLVED FIXED

The aero on firefox breaks from time to time. It has happened to me on two different machines (both Windows 7 64bit). It doesn't always break for the same reason, but I have figured out a way which I think quite consistently breaks it. This has happened to me before Beta5 too, I think it has happened since the first beta. It happens both with HW-acceleration enabled and disabled.

Reproducible: Always

Steps to Reproduce:
1. Maximize Firefox
2. Connect/disconnect external monitor (probably works with resolution change too)

Actual Results:  
The aero theme is now broken, see screenshot.

Also, if I open a new window, that window will have working aero. See the screenshot, it shows two windows side by side, one broken and one working.

This is almost certainly a dup of bug 545892, but we can check again when that's fixed. FWIW, I see this all the time also.
