Hi, you can try to set the variable “__GL_SYNC_TO_VBLANK”
to a non-zero value that should force the nvidia driver to swap
the buffers while the vertical retrace takes place. Might help. But
as long as that happens only when you move the window, I think this could be a “normal” behaviour ( it might
also depend on the window manager you’re using). Regards, Toni From:

[mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Dear all, my todays e-mail is not specific for OpenSG but I am confident that
somebody is on this list who can help me. I installed Linux on my workstation, downloaded the OpenSG sources and
compiled them. When I move the glut-window or run the tutorial
"02move" I get a strange flickering. It looks like the image is
sometimes generated in bands which are shifted against each other. I find it
very hard to describe, so I attached a small image. Does somebody have an idea what this is? Help would be appreciated.
Thank you very much! Setup: HP xw9300 with 2x NVidia Quadro FX4500, Scientific Linux (kind
of RedHat) with Xorg. The graphics driver is new from NVidias
homepage. I have one screen 1600x1200 per graphics board. Kind regards, Bjoern Zehner
