[PD] GEM causes soung glitches

[D G]

Hey thanks for the Answers

Charles you mention looking at /var/log/Xorg.0.log there are many lines
concerning GL. Any ideas to which shuld I edit.

Any GUI based or terminal command to enable GL hardware acceleration and
rendering for openGL?


By the way I forgot to mention that the same patch works perfect on the
same machine running with Win7. So it is not a hardware problem. It is for
sure configuration.

Ill also try the two PD instances

But i think it is more likely to be the acceleration of the graphics card.
