Description Andreas Sturmlechner 2023-04-10 12:38:31 UTC

This leads to me inadvertently changing volume to around 50% instead of switching to the desired task rather often.

Additional observations:
- regular window previews without multimedia controls sometimes float way above the actual panel as if they were leaving space for such controls
- I haven't seen that in X11 sessions yet

Weird. Can you attach a screenshot that shows what it looks like when this is happening? Thanks!

I have seen this too.

I noticed that if you open a tooltip with media controls, let it close, then open a tooltip without that, it opens "floating above", at the same y-position as the first tooltip.

If you let that tooltip close and open it again, it opens normally. Now if you let that close and go to a tooltip with media controls, it opens overlapping the task below, again at the same y-position as the first.

So clearly the y-position is getting reused across instances when it should not be. Exactly where it is happening I'm not yet sure.

Just a note since you changed $summary: dolphin in screenshot #2 would not contain media controls at all, but is not touching the panel.
