this is the short info window, that wont vanish

Version:           unspecified (using KDE 4.4.5) 
OS:                Linux

When hovering mouse over date & time in panel a small window appears, that does not vanish anymore. I have to move the mouse again to an item in the panel (no matter which), until the short info is showed. Then the date & time window gets 

Reproducible: Sometimes

Steps to Reproduce:
Steps to reproduce:

1. Move the mouse over date & time in the panel
2. Let it rest there until a small window appears showing date & time
3. As soon as it appears, move the mouse away

The window will stay there (see the screenshot i added).

But you have to try a couple of times to see this bug appear. I tried to count the seconds, but it was not possible for me to tell the exact time needed for it. I think it is the moment when the window tries to appear, and while it does, I already move the mouse away, so it gets stuck. It seems to work best, when you do need less than a single second to let the window appear, and then move the mouse away. But this bug only appears, when hovering the mouse over date & time, and seems not to occur, when hovering over other panel-items.

My settings for date and time show also the seconds. My settings to panel allow other windows to overlap it. See screenshot for my settings. 

Actual Results:  
The short info stayed forever, until I hovered the mouse over another item.

Expected Results:  
The short info should vanish after a while.

My widget style is slim glow. My panel allows other windows to overlap it and comes to front when moving the mouse to the bottom.
