Bug Description
Binary package hint: compiz
I experience screen tearing and other issues when using the unity desktop on natty, or the classical desktop with effects. The problem seems to be compiz specific, it does not seem to be present on the no-effects classical desktop as far as I can say.
When I run glxgears with compiz on, it runs awfully slow, I've never seen that before. It seems to run normally on the no-effects desktop, although CPU usage is rather high, but perhaps that is normal, I don't know...
It also seems that parts of the screen don't always redraw correctly – e.g. sometimes when the unity desktop loads, there is a corruption visible – its as if you took a screenshot of the desktop , enlarged it and put a part of it over the bottom right edge of the screen. It redraws, fixing the corruption, when I right click on that area.
Similar effects do sometimes manifest themselves on other occasions – when a certain region of the screen just does not redraw properly.
I am on toshiba qosmio x500 with nvidia GeForce GTS 360M if that is of any use...

My issue seems to be related. It seems that when enabling any Compiz plugin that requires a screen update, it corrupts the graphic of the upper panel (not sure what to call it in Unity since there is only one....and it's not really a panel) as can be seen on the attached screenshot. And the wobbling window effect shows teared movements which were not there before.
