BERYL Response Times

[vehemens]

I seeing BERYL window moves and cube rotation hesitation as much as several 
seconds after running for several minutes.  Also after running for 30 minutes 
or so, I see a significant increase in response delays.

I've read that BERYL has some problems, but none mention this type of runtime 
problem.

The system is somewhat low end (XP 2100, 512MB, RADEON RV250), but it doesn't 
appear to be a resource problem.

Is anyone else seeing this?  If not, what's your configuration?
