rectangles appearing in side windows not in focus

[Albert Vilella]

Hi,

When I plug my laptop to an external screen, and resize any of the windows I have, the other windows in the external screen that are not in focus sometimes show up rectangles of image corresponding to the background desktop or to the window under them.

See for example the tearing of the terminal windows on the top left in this screenshot. This happens when I move a window around the other terminal windows.

Hey avilella,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.
