Comment 4 for bug 225858

The compiz redraw-problems seem to pop up every time an application tries to use the full screen. That's why the screensaver triggered it in my case, but I also get the same issues when I try to view a full-screen image. So it seems to be the same problem that is described here: http://www.nvnews.net/vbulletin/showthread.php?t=122336

Reverting to version 173 of the nvidia driver seemed to resolve this particular issue for me, although I didn't test very well because this driver messed up scrolling in most applications, making it impossible to work. Updating the nvidia driver to the current stable release (180.22, taken from https://launchpad.net/%7Emythbuntu-trunk-0.22/+archive/ppa) also seemed to solve the problem, but caused stability issues on my system. (These were possibly interrupt-related, after a while my USB devices tended to lock up, or the entire X.org just crashed or hung for no apparent reason.)
So I switched back to the default 177.82 nvidia driver and upgraded compiz to the latest git-snapshot (0.7.9-git20080918, following http://ubuntuforums.org/showthread.php?t=971379). This seems to cause the least problems so far. There are still some annoying window-update issues when I open a lot of windows, but other than that everything works as it should with desktop-effects switched on.

I guess this bug is a combined problem of the current compiz-fusion (0.7.8) and the nvidia 177.82 driver in Intrepid, as updating either seems to make it go away...
