Description Philip Muškovac 2012-01-04 16:03:03 UTC

Version:           unspecified (using Devel) 
OS:                Linux

Qt 4.7.4 KDE 4.7.95 Kubuntu precise
See screenshot. There were 2 gwenview windows open. After closing one of them (at the position that currently ended up being highlighted by chance) then entries below it correctly slided up to fill the empty space, but the entries above it also slided down leaving an empty space in the middle (The top 8 icons are kickoff + 7 launchers) and causing the remaining gwenview entry to now cover the entry for the open firefox window making it unaccessible.
This happened in early 4.7 too, then stopped at 4.7.1 and is now back since 4.7.90
Once you open or close another window the entries fix their positions.

Reproducible: Sometimes

Steps to Reproduce:
Happens randomly when closing a window with like a 5% chance. Not tied to any specific application

Actual Results:  
When closing a window both the entries before and behind it move to cover the now empty space

Expected Results:  
Only the entries behind it should move.

Settings:
Force row settings: false
Show tooltips: true
Hichlight windows: false
Maximum rows: 1
Grouping: By Program Name
Only when the taskbar is full: true
Sorting: Alphabetically
Only show tasks from the current screen: false
Only show tasks from the current desktop: false
Only show tasks from the current activity: true
Only show tasks that are minimized: false

Thank you for your report.
