Bastien Montagne (mont29) triaged this task as Needs Information from User priority.

Just in case, be sure to have the latest GPU drivers installed.

Pretty sure this is another OGL/driver issue, please try to put this software OGL next to your blender.exe and see whether the issue is gone…

newest driver: 337.88

using software OGL don't resolve the issue, but instead of weird pattern i get black
i also get black on my second card in laptop : Intel HD 4000

is there someone on win7x64 with nvidia mobile (or not mobile) card that could confirm this?

Campbell Barton (campbellbarton) renamed this task from two windows layout bug to OpenGL Multi-Window Error.

Tested some more and I cant reproduce this bug, its one timer corupt blend file. I suggest to close this bug.

Closing then (we usually can’t do much about those OGL bugs, anyway… :/ ).
