Description Matthias.Schroder 2017-08-30 13:26:53 UTC 
Starting glxgears on a centos 6 box opens an XQuartz window that display the usual gears, but the gears never move. Stopping the execution of glxgears on the linux side leaves the windows with the gears open.

The framerate announced by glxgears appears to be incorrect:

host[129] glxgears
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
20598 frames in 8.7 seconds = 2364.560 FPS
536 frames in 13.0 seconds = 41.158 FPS
766 frames in 11.0 seconds = 69.496 FPS

Oops, now I notice that minutes after I have stopped glxgears I see a tiny movement of the gears, and then the window disappears.

Any hints how I can debug this?

It's likely not a real issue.  This is a common observation.
