Public bug reported:

Binary package hint: compiz

I upgraded from Ubuntu 9.10 to Ubuntu 10.04, and since then I seem to be
getting a strange artefact.

When I switch Windows with Alt+Tab, regardless of the used switcher (I
used both the Ring Switcher and the Static Application Switcher so far),
sometimes, without a specific pattern, the window I switch to stops
repainting itself. That is, I can click in it, type in it, etc., and it
updates itself internally, but it doesn't repaint to show the changes.
It feels as if it's frozen.

After I Alt+Tab again, and switch to it, I can see the changes I made
while it was frozen, and then everything works for a while, until next
time it decides to do it.

Now, I don't know if it's compiz or nvidia at fault here. I tend to
think it's nvidia, because I don't get this behaviour on an Intel video
card running the same software with the same settings. And if I get a
new nvidia driver and it stops doing this, I may even close this bug.

Packages:
- nvidia-current 195.36.15-0ubuntu2
- compiz 1:0.8.4-0ubuntu15
