I made some further investigations for the nouveau driver today.

Kernels 3.5.0-10 to 3.5.0-12:
The issue is present with a corrupted screen and massive logging of PFIFO_CACHE_ERROR messages.

Kernel 3.5.0-13
The issue seems gone, i.e the nouveau driver again!

It seems that the fixes for kernel 3.5.0-13 (two bugs) also fixed this issue!
My guess is the framebuffer recycling issue being fixed.

The issue also is present in kernel 3.6, but never mind as 3.5 will be shipped for Quantal.
