Default Strange compiz performance issue

With .19 compiz fusion performance is great again... for a while.

Performance gradually deteriorates after starting compiz, and seems to stabilize around 3-5 fps after about one minute. Moving the cube around for a bit resets this, and makes everything animate and move smoothly again, restarting that performance degradation cycle.

This also triggers a second bug. Sometimes when I scroll up or down in an application, the part that wasn't visible before I scrolled doesn't get drawn at all, or lags behind quite a bit. It happens more often (almost 75% of the time) when that performance degradation is at its worst, and I'm almost sure I've never had it just after starting compiz or moving the cube. It actually happened while I was writing this post, so I took a screenshot. You can see the bug appearing near the bottom of the page.

EDIT: Forgot to mention that just clicking the page, or creating any other kind of event (including scrolling again) draws the page correctly.

Any ideas?
