It's probably something unrelated to quartz directly, because I'm
experiencing similar behaviour with xv, but only with video filters
enabled. When no filters are active, everything is fine. I haven't been
able to trace the origin of this bug yet, so I'm afraid it's all I've got
now. Please see if it behaves similarly with vo quartz.
