Version:           unspecified (using KDE 4.7.2) 
OS:                Linux

Since 4.7.0, thus thorough 4.7.1 and 4.7.2, TaskManager behaves strangely. The icons are placed randomly with spaces between them. Sometimes, this forces the two columns. See the attached pictures. 

Best regards,
Octavian

P.S. In one of the pictures, there is a red question mark. this has been drown on the picture to show the space between icons.



Reproducible: Sometimes

Steps to Reproduce:
It happens after few hours/days of usage

Actual Results:  
Spaces between icons in the TaskManager

Expected Results:  
Icons should not be separated by spaces.
