Hi, All.  We're seeing a problem running opengl on a remote SL6 system when the local system uses the proprietary nvidia drivers.  This does not seem to be a problem with remote SL5 systems.

The problem seems to only be when sitting at a local system with the nvidia drivers (tested with local SL5, SL6, and OS X) and running opengl on a remote SL6 system that doesn't have the nvidia drivers.

I think the example below probably demonstrates this better than my description.  Any suggestions would be greatly appreciated, and please let me know if there is any more information we can provide.

Many thanks,
Devin
