Version: (using KDE 4.3.0) OS: Linux Installed from: Unlisted Binary Package Sometimes, when a window is closed the taskbar keep on showing the task as it hasn't been closed, but minimized. Obviously when the task is clicked to maximize the window, nothing is shown. As I've said it only happens sometimes, not always. The only difference between the default configuration and the one I use is that mine only show the tasks of the current desktop. I don't know exactly in which conditions it happens, so feel free to ask for information you may need.
I've experienced this bug too on trunk. I've two taskbar (one for each monitor, I'm using twinview by nvidia). Both taskbar are configured for displaying only tasks on the same screen. Usually I've seen the bug when I recompile KDE but it could be only a coincidence. After restarting plasma-desktop the taskbar is correct.

@FiNeX: so you too experienced this bug. We are tracking it at bug 202199. (can you confirm it is indeed the same?) So far, I have not seen this again since the 4.4update a week~ ago. Regards
Thanks Dario. Yes, is the same bug. Last time I've seen this bug was two or three days ago. *** This bug has been marked as a duplicate of bug 202199 ***
