Thanks for the bug report. I'm not able to reproduce this on git-master. It may be dependent on the panel size. 

Does this still happen on Plasma 6.5.3 or later?
If it does, what is the size of the panel in question?

Thanks.

I will try, as soon as I have Plasma 6.5.3 installed.

BTW, this does not occur, when the panel-clock displays seconds. I guess in this case the refreshing of the clock, leads to a panel-update every second too.

For Plasma 6.5 the problem remains!

I did install a new distro and can confirm now, that the problem persists even in Plasma-Version: 6.5.4.

And on a side-note: I find it problematic, that the reporters of bugs are forced to install a new distro or otherwise their reported bug gets automatically closed as RESOLVED WORKSFORME.

For distros that don't support the latest versions of Plasma you have a couple of options, depending on the distro, without having to reinstall
1. If the update will be provided in a short period of time, just wait and re-test when the system is updated
2. If the distro intentionally keeps the Plasma versions back (such as Kubuntu or Debian), it is the responsibility of that distro to maintain the older versions of Plasma software and provide support. In this case, while the KDE bug would be closed, you can open a bug with the distro.

In any case, let's keep the conversation focused on the bug.
I'm not able to reproduce this on Plasma built from git-master, on Solus. I have a couple of questions to try to narrow things down.

What distribution do you have installed now?
Also, what do you have set for animation speed in System Settings - Quick Settings?

Thanks!
Comment 11 Thomas Vde 2026-01-10 07:05:19 UTC
In the case of Debian or Kubuntu: Is it a realistic expectation, that they will fix such a KDE-bug? ... Somehow I strongly doubt this. Am I wrong?

Ok, yes, lets narrow it down!

More about my system: 
Operating System: KDE neon User Edition
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1
Kernel Version: 6.8.0-90-generic (64-bit)
Graphics Platform: X11

And the animation speed is set right in the middle. ... But changing it, did not eliminate the behavior (though I did not restart Plasma, just pressed "Apply").

PS: If you have more questions, I will always answer them, even if it sometimes may take a couple of days.

Thanks for those details. I'll leave this open so others can try to reproduce.
