Slow vncviewer? Enable composite

Posted by rawhidewatch on March 26, 2009

Apparently vncviewer is REALLY SLOW, rendering something in 2D that causes X to use 100% CPU with i945 video (possibly other cards too?)

Enable compiz and vncviewer will be suddenly fast again.  Adam Jackson reportedly is working on optimizing intel driver performance.  He says rendering directly to the front buffer is bad right now.  This is being tracked in Bug #490839.
