glitch in blender menu

Mostly when maximizing blender (you might need to try a few times) the menu at
the top is full of artifacts and glitches.
It is independent of DE or any compositing effects because I tested this under
compiz and openbox (without compiz) and it always occurs.

I have attached screenshots for better understanding.
I have tested it with both a HD4770 and a R7 260x graphics card (and I think it
also happened on my laptop HD 5xxx).

My bugreport on the blender bugtracker: https://developer.blender.org/T37504

This should be really easy to reproduce. I use Archlinux with the latest
software.
