I've seen two different behaviors.
One is when the window contents is the frame snapshot of the underlying  
desktop
when the window receives show event. Erm... I ignorantly call that
'false compositing method'. When window is moved, its contents isn't  
changed,
so the window isn't transparent.

The other is somewhat different. I couldn't reproduce it anymore.
The contents is like black and white vertical lines were seriously
distorted horizontally... Yes, lame description indeed. But I couldn't  
recognize
any patterns in what I saw.

Somewhat contradictory... I think it has 256M.

Yep, that's how I run it now. And I did turn it off in opera:config.
