Does it happen if you start thunderbird in safe mode?

No, starting Thunderbird in safe mode leads to correct displaying of the UI.

Daniel, 
Does Disabling HWA in Tools | Options | Advanced helps help you?
Are you sure you have the most current driver?


I may file a new bug, because I am seeing horrible paint delays with typing and displays in my 38.0b1 candidate build on thinkpad with NVIDIA Quadro 1000M, non-aero theme, starting with . According to Device Manager and windows update my drivers are current. I have not seen this when using Thunderbird trunk, so somewhere in gecko 39 I get fixed.

I recently retested with HWA enabled.  I did not see delays. But there are some trivial paint issues.

Safe mode resolved Daniel's problem. So it is fair to assume this was HWA related
