Hi,

I do also see something that corresponds quite well to your description
of an occasional "glitch". It is very annoying, and it is like you swap
from a mode with fine stereo to a mode where left and right eye are not
properly represented and you cannot see real stereo.

I just wonder if that is a problem with
- nvidia driver
- stereo shutter / video driver synchronization
- VMD ( I guess not .. ? )
- high load on the machine

because for now it seems a lot more frequent when I run eg an IMD simulation
on the same machine, eg when it is under high load.

Anybody else sees this ?

The annoying thing in my case is, once it has gone clear for a frame, it
does not immediately switch back to proper stereo. So you really can't
use it when this happens.
