System freeze possibly due to memory corruption

[Peter Sasi]

Binary package hint: libgl1-mesa-dri-experimental

System is Ubuntu 10.10 Maverick, just upgraded from Lucid, 4GB RAM Lenovo ThinkPad T61, Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50GHz, nVidia Corporation G84M [Quadro NVS 140M] (rev a1), kernel 2.6.35-22-generic, using Nouveau driver, Both single monitor (laptop) and dual screen (laptop + external DVI or VGA) setups.

After installing libgl1-mesa-dri-experimental version 7.9~git20100924-0ubuntu2 for 3D support system locks up in random amount of time (2-30 minutes).
There is a visible image corruption on the background. Sometimes already on boot, sometimes only later. Sometimes none, sometimes the lower part, sometimes the whole background. It occours much more often with dual screen, using laptop+DVI.

The time it takes to freeze seems to be related to images used: if I load a 3000x3000 jpg (satelite image) in firefox it locks up immediatelly, consistently. It does freeze ony using eg. 2 gnome terminals, 1 firefox and 2 nautilus windows (no explicit 3D apps other than compiz).
