On nv4x with a msaa visual after a while the gpu locks up, attach gdb to
impress shows it is hanging waiting for a fence which never comes.
Killing ooimpress at this point works exactly once, trying to do any
3d operations after killing impress will lockup the entire system.
This needs further investigation, but for now disable msaa because no
msaa is better then crashing the system.
