In the 'present windows' desktop effect, you can drag on an empty region of a desktop (i.e. a region that isn't covered by a window (I have the 'use present windows effect to layout windows' option enabled)) to move all windows in that desktop to another desktop. The expected behaviour is that this only applies to windows in the current activity. However, it applies to windows in all activities that are on that desktop. Steps to reproduce: 1. Create 2 activities (say 'A' and 'B') 2. Open a window on a desktop (say desktop '2') of activity A 3. Switch to activity B, and open a few windows on desktop 2 4. Activate the desktop grid effect, and drag an empty space in desktop 2 to desktop 1 5. Switch to activity A Observed result: The windows in activity B, desktop 2 have moved to desktop 1. The window in activity A has also moved to desktop 1. Expected result: The windows in activity B, desktop 2 should move to desktop 1. However the window in activity A desktop 2 should stay on desktop 2.
I'm not sure whether this is a bug. I can see users wanting both behaviors. Very unsure.
Hello, I also think that this is a bug. As I understand activities, they do exist to separate different windows for different tasks (e.g. projects). So windows organized in activity A usually are completely independent from windows in activity B. So if I want to move all windows in activity (project) A from one desktop to another I do not want the windows in project B to be moved. (I was really astonished about the current behavior.) There is only one exception that might make the situation tricky: Windows that are configured to appear on all (or some) activities. In this case I think they have to be moved on all of theses activities. But I would expect that this happens automatically if a window is moved on only the current activity anyway. At least if I move one window manually from one desktop to another, this window is moved on all activities that the window is configured for. If you are unsure about the right behavior, it should be configurable in the desktop grid effect settings. But for me it is no question that the current behavior feels wrong.

Great! Thank you for the fix!
This bug happens again in the QML rewrite that was introduced in 5.24.90. Should I open this bug, or file a new one?
Oops, looks like that got lost in the QML port, yeah. We can re-open this one.
