Public bug reported:
Binary package hint: xserver-xorg-video-intel
After upgrading to natty the screen is now sometimes corrupted. I can't
trigger this with a fixed set of steps yet but it happens most when
switching virtual desktops, coming back from suspend or connecting or
disconnecting an external monitor. It cleans up completely by switching
to the text console and back.
A screenshot is attached of when this happens. The corruption is always
of the form of something not having been refreshed/drawn in, never that
there is something out of place. So sometimes google chrome will lose
some of its decorations or a window won't fully show up after having
been alt-tabbed in. For windows, giving them focus usually causes a
redraw that fixes the corruption. For the panel any element used gets
refreshed but the empty portions will only be refreshed with a vt
switch.
I'm using the classic gnome desktop without compositing. I've noticed it
in google chrome's decorations a lot and that does it's own drawing so
it could be related. I filed this under the intel driver but it could be
a core xserver bug. Would trying unity on the same system help narrow
down the issue?
