It's still a userspace application that's at fault...

Hello,

I have the same issue. In addition Xorg.0.log contains the following messages:

(WW) intel(0): i830_uxa_prepare_access: gtt bo map failed: Invalid argument
(EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: Invalid argument.

You won't find the offending code in the upstream driver...
