I noticed a somewhat weird behaviour of my Plasma’s animations for minimising (and then reopening) windows, whenever I connect and/or disconnect a second screen. I’m currently using the “Magic Lamp” animation, but I noticed the same behaviour with the “Scale” animation.

Exact description of my observations:

  • When minimising a window, Plasma would play a little animation of the window disappearing into its respective spot.
  • Connecting a second screen whose desktop also contains a bottom panel (an Icons-only Task Manager), causes the “focal point” (for lack of a better word) to shift to that second screen’s bottom panel.
  • The minimising animation would now be played normally, however, the window would disappear into the second screen’s panel’s icon.
  • Disconnecting the second screen again, causes my Plasma to lose this “focal point” altogether and the “Scale” animation would no longer be played at all, while the “Magic Lamp” animation still works, but “sucks” the window into some seemingly random point on the top of the screen.
  • Everything is back to normal after a reboot.

Am I missing some setting here, or am I just experiencing a weird KDE Plasma bug?

Edit: Another thing that just came to mind and that I think I should mention is that this “issue” isn’t new. It was not caused by an update or by installing some weird package. It’s always been there as far as I can recall, I just never got around to asking.

Does this also happen in a newly created user? (I can’t test as I only have 1 monitor with 6 desktops)

If yes, please read this:

Especially the section What’s this Upstream / Downstream business? and file a bug upstream…

I posted this stand-alone first, but I had meant to reply to you, so I deleted my previous post and posted it again:

Yes, it happens there as well, as soon as I add an Icons-only Task Manager to the second screen’s desktop. I wonder, though, if it happening for a newly created user is really useful information. If I suppose that some kind of default setting that I just don’t know about is causing it, wouldn’t I expect it to happen with any user?

Anyone who responds to your post is automatically informed of all replies. No deed to do that in the future, no apologies needed, just informing you. :innocent:

Yes, because that means it’s a bug in Plasma itself and not a weird combination of customizations that you did on your own user.

You know what to do now… File that bug upstream…

Therefore, I’ve marked this answer as the solution to your question as it is by far the best answer you’ll get.

However, if you disagree with my choice, please feel free to take any other answer as the solution to your question or even remove the solution altogether: You are in control! (If you disagree with my choice, just send me a personal message and explain why I shouldn’t have done this or :heart: or :+1: if you agree)

:innocent:
P.S. In the future, please don’t forget to come back to your question after your issue has been solved and click the 3 dots below the answer to mark a solution like this below the answer that helped you most:
Solution
so that the next person that has the exact same problem you just had will benefit from your post as well as your question will now be in the “solved” status.

I would have come back to mark a solution, however, at the time of my second post, I still had a question and thus didn’t consider the topic solved then. Now, with your second reply, I can accept your answer as a solution and I’ll post the bug over at the KDE place. Thank you for your help, as always! :slight_smile:

My apologies: as I see too many “unsolved” (which are really solved, just not marked as such) questions, I’m jumping the gun most of the times… :sob:

Someone has to do the cleanup! It’s all good, mate!
