Description Matthias Kretz 2013-01-17 09:46:17 UTC

If you switch activities, so that a window has to leave a tab group, the tab group is lost.

Reproducible: Always

Steps to Reproduce:
1. You need two activities and two windows to reproduce the problem.
2. Put one of the windows on both activities, the other window only on one activity.
3. On the activity with both windows, tab attach one of the windows to the other window as Tab.
4. Now switch activities (fine: window disappears).
5. Switch activities back to the one with both windows. 
Actual Results:  
The tab group is broken up.

Expected Results:  
The two windows should still be in the tab group - independent of activity switching.

@Thomas: maybe do not allow to group windows which are not on the same activitity?

Moving to activities since it's not yet defined how the WM relates to activities.

Comment 3 David Edmundson 2022-07-27 15:14:03 UTC

We no longer have tab groups
