Attachments: After closing a window, the Processing icon has moved on top of the Ksnapshot icon, leaving an empty spot above the Firefox icon
See the circled area; the KRDC icon and text is over top of the Okular icon and text. (You may have to zoom in to see it clearly.)
See the circled area; the KRDC icon and text no longer overlap the Okular icon and text. Opening and/or closing pretty much anything will clear up the overlap (making it uncapturable with ksnapshot.)
Overlap of task frames in TaskManager
For good measure, here's a screenshot of a gap.

Description Otso Helenius 2012-07-02 16:03:39 UTC
When closing a program, the task Manager moves program icons on top of each other. This happens when activating a program which is on the bottom of the list, switching to another program which is above it and closing it. The bottom icon moves on top of the icon above it and an empty space is created in the list. This can be reproduced every time.

Attached you will find a screenshot of the bug.

Reproducible: Always

I can confirm this, or a very similar bug, exists in KDE 4.9.3 (and many previous versions). The effect is that there can be gaps or overlapping icons in the task manager.

However, I can't always reproduce this bugs. Also, sometimes I get a gap but not overlap, and sometimes I get overlap but no gap. I haven't found a pattern. I will be attaching two more screenshots.

I have the same problem. Sometimes I get gaps, sometimes overlaps, usually both. It tends to happen when I close a window (about 15% of the time), though, and everything goes back to normal once a new window is opened.

I reckon that this is a duplicate of Bug 224447 and (allegedly) will be fixed in 4.11.
