I'm experiencing this problem since I upgraded from 11.04 to 11.10.
I thought it had been a bad upgrade and I then did a fresh install and the problem remains.
I've also experienced this on both Kde and Gnome sessions.
Sessions without acceleration like Ubuntu 2D are not affected.
My VGA card is :
VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04)
Note: I'm not going back to Windows over this! I'd rather poke myself with a burning stick.
