Comment 22 for bug 813343

I just wanted to note that I no longer have the "covered by black" problem
in 11.10 beta2, however I still do have issues when adding/removing
monitors to TwinView. They're mostly visual corruption that go away once
the transition is over. I suspect these are different issues than the one
reported here though.
