Hmm, I'm actually having this same bug on both of my laptops, and I don't think it's a driver bug but compiz or the xserver. For me, when I kill compiz remotely, the screen flashes with the desktop contents and then when compiz is respawned it leaves me a screen with the background and functional mouse (the cursor changes as it passes windows that are "invisible"). This of course after blindly opening the screensaver :)
