Bug Description
Binary package hint: unity
When running unity, I get all kinds of graphical glitches related to parts of the screen not being repainted when they should (is this something the xdamage extension is supposed to handle?).
For instance:
1. When I log in, two-thirds of the screen background on the first monitor is clearly not painted properly - see attached screenshot.
2. When I resume from suspend or switch users the entire unity launcher bar is often shown as a sea of colourful but random pixels. (If I press the Prnt Scrn button the bar is redrawn before the screenshot is taken so I haven't got a screenshot.)
3. When the screen goes blank after 5 minutes (ie the screensaver kicks in) and I move the mouse to bring it back, everything mostly stays black (firefox, the background, etc). For instance, I might get the firefox bookmarks sidebar showing and the tab headers, but the rest of the screen will be black.
This quite possibly could be a problem with compiz or nvidia-current 270.30 rather than with unity, but it only seems to happen on my unity desktop - classic mode works much better.
Opening applications, moving the mouse or windows around etc eventually gets the screen repainted. It just looks messy.

This is also happening in a VirtualBox VM, so it is not specific to nvidia drivers.
