Bug#837786: mutter: Issues repainting the display on mouse movement

[Roman Pavlík]

Version 3.22.0 (currently from unstable) still affected.

Today`s update to Mesa 12.0.3-1 didn`t help.

I am not familiar with Linux graphic stack.

Frames that should not be displayed (because they are few seconds old) 
are still flickering into current proper frame, seems like framebuffer 
is not correctly flushed or something like that.
