Description Stefán Freyr Stefánsson 2014-01-13 12:53:44 UTC

I'm running Kubuntu 13.10 (KDE 4.11.3) and I'm seeing that when I switch between virtual desktops my windows get ungrouped in the taskbar. Closing one of the windows that should be grouped brings back the grouping but then switching from and back to the virtual desktop ungroups everything again.

Reproducible: Always

Steps to Reproduce:
0. Configure the taskbar to show only the windows on the active virtual desktop (check the "Only show tasks from the current desktop" in Task Manager Settings)
1. Start a few windows (for example a browser) until they get grouped on virtual desktop 1
2. Switch to a different virtual desktop
3. Switch back to virtual desktop 1
Actual Results:  
Windows get ungrouped

Expected Results:  
Windows should stay grouped

I can confirm the issue. For me, it does not work as soon as I have changed windows (added, closed, changed title) on the other workspace: when I switch back to the first workspace, the windows have lost their groups and are not re-assembled.

This still exists in the Kubuntu packages (KDE 4.13.0).

Plasma 5.7 ships a fully-rewritten Task Manager backend which should resolve these issues. Please re-test with the Plasma 5.7 final release and feel free to reopen if problems do persist after all.
