I have this weird display issue on my x220 machine, only on the first screen :
I'm using a kernel 3.11 and the intel xorg driver 2.21.15.
Is this a regression?
I reproduced it first on a 3.2 kernel with an older version of the X driver.
I also remember seeing that bug on Ivy bridge (on an internal project) when switching a window fullscreen (which disable the composition).
So it appears to have been around for a while, this is just the first time I manage to reproduce 100%, an interestingly it only affects one of the monitor.
Looks like http://lists.x.org/archives/xorg-devel/2011-June/023218.html (rebased as http://cgit.freedesktop.org/~ickle/xserver/commit/?h=dri2-invalidate&id=eb256400317b98e999b5dabe06a82970bd922068 )
I'm having the same issue. It's only on the first screen as well. PNY Nvidia GeForce card. Gnome 3.10.1. Would like to have this fixed. Sometimes it feels like I'm gonna have a seizure.
