Description Mike 2008-11-26 18:22:04 UTC

Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

If you resize the panel to very small and then back to large, it often causes the desktop to be cropped with most of it being black.  A portion, roughly the size of the panel is painted at the top, the rest is black.

I have also seen plasma crash when resizing the panel very small, but I am afraid I closed the bug window.

It might be that something is resizing the plasma window when the panel changes size.  I have a lot of moving and resizing problems with the panel.  Restarting plasma corrects it.

I am on a twinview setup with nvidia drivers.

===========================================================

Here is the output from plasma.
