[Bug 653242] [NEW] Panel puts ghost shadow on Desktop

[Thilo-Alexander Ginkel]

Public bug reported:

Binary package hint: kdebase-workspace

While I initially observed this bug on my Desktop PC running Kubuntu
10.04 + backported KDE 4.5.1 I am now able to reproduce it using the
10.10 release candidate running inside a VirtualBox VM. This rules out a
graphics-driver-related issue.

>From time to time, after logging into my KDE session, the shadow that is usually drawn behind the Plasma Panel at the bottom of the screen appears detached from the panel in the upper left quadrant of the screen. My panel is set to auto-hide and the shadow appears and disappears when the panel shows and hides. To temporarily correct the issue (until the ghost shadow decides to show
up again), either change the panel alignment from "Center" to "Left" to "Center" (but I guess any alignment change will do) or log off and log on again (while the latter comes with a certain probability that the issue will immediately pop up again).

When inspecting the list of existent windows, one can actually spot a
window, the dimensions of which correspond to the dimensions of the
shadow.

For an example, refer to the screenshot at:
