Description of problem:
Moving the cursor up and down over the K-menu sometimes "wipes out" the menu
texts and icons. Moving over them again restores them.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Click the "K" icon in the panel.
2.Move to an entry near to top, wait until the secondary menu appears
3.Move down the main menu, wait again for the secondary menu
4.Move cursor up 


Actual Results:  Moving cursor wipes the menu clean to the background color.

Expected Results:  Cursor moves, the menu entries remain as they are.

Additional info:

The bug seems to be timing-sensitive, sometimes a couple of up/down moves are
needed, sometimes this happens immediately.
