Hello, I posted this in the New UI bug report section, but at closer examination the old UI does it as well. Large triangular sections of the screen seem to disappear, leaving a blank-black space. Here is a screenshot to help explain:

I can get more for future reference if need be.

I'm running VO on a computer way underspec, 600MHz G3 with an ATI Rage128Pro2 graphics card. I also just upgraded from Mac OS 10.4.2 to 10.4.5, this is when the bug started happening - after 4.5 was installed. Thanks a lot and keep up the good work!

Turn it off!
