In certain situations, grey lines appear around the X desktop window and
do not disappear until X is restarted.
The easiest way to reproduce this is to select a file on the desktop and
press F2 to rename it - the lines appear instantly.
Other ways to reproduce it include changing screen resolution and video
modes (see below).
This happens both in a VirtualBox VM running Lucid (I can see it in both
full-screen and windowed mode) and on my main laptop. On the laptop, it
happens whether I use the nvidia or the nouveau driver.
Other information about causing it with mode changes with nvidia-
settings are:
When I use nvidia-settings to change screen resolution in Lucid, grey
lines (perhaps two pixels wide) appear around the border of the X
window. For instance, with left and right monitors configured, this
means I get grey lines around all but the right edge of the left monitor
and all but the left edge of the right monitor.
The lines appear as soon as the resolution change takes place (while
nvidia-settings is asking you to confirm the change) and persist if you
cancel the change and return to the previous mode.
The lines also appear if you have two monitors configured, physically
remove one, choose 'Detect Displays' and apply the changes with no
change in resolution for the default monitor.
Restarting the X session is required to remove the lines.
Note that the same nvidia drivers (195.36.03) do not exhibit this
behaviour in Karmic with the 2.6.33, 2.6.32, or 2.6.31 kernels.
