The attached screenshot shows a VM running Lucid. In the top screenshot,
X has just started up and there are no grey lines. In the screenshot
underneath, I have just pressed F2 to change a filename. The most
obvious grey line is the one that has appeared on the left (zooming in
makes it more apparent).

** Description changed:

+ 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 so it
- seems to be an X/nvidia issue.
+ behaviour in Karmic with the 2.6.33, 2.6.32, or 2.6.31 kernels.
