Description Frank Schaefer 2013-01-28 18:22:51 UTC 
Closing an application sometimes leaves a gap and/or overlying task fields on the taskbar.
I would say having lots tasks and multiple rows increases the chance to trigger this, but I also get this with only two or three tasks and a single row.
The fact that I'm using a slow onboard graphics card with desktop effects enabled could also be relevant.

If I had to guess, I would say it looks like a race condition.

This bug is present since at least KDE 4.4.

Reproducible: Sometimes
