ADDITIONAL INFORMATION

Comment 1 Nate Graham 2023-04-24 18:41:38 UTC

Does this happen for Panel widget tooltips too, such as the one seen when hovering over "Application Launcher" and "Digital Clock"? Or does it only happen with tooltips for System Tray icons?

Comment 2 Clementine 2023-04-26 01:19:11 UTC

Sorry,but after a system update to tumbleweed 20230422, I cannot reproduce it again. It has just been fixed, magically.

Before that, only system tray icons have this issue.

Comment 3 Nate Graham 2023-04-26 14:04:36 UTC

All right, let's keep an eye on it. If you encounter the same issue again, feel free to re-open this bug report.

Comment 4 Clementine 2023-07-28 16:42:14 UTC

It happens again. (maybe many days ago)

A similar issue is  https://bugs.kde.org/show_bug.cgi?id=468811. about taskbar grouped tasks' texual list.
Also, popups for volume, brightness change, status of touchpad on/off also have similar issues.

It seems like, "popup"s have the same problem

An important Note is that these bugs are only produced on plasma(X11), not plasma(wayland), with (maybe old intel graphic cards, maybe?, I use a laptop with intel i5-6300U and Intel Corporation Skylake GT2 [HD Graphics 520]). 

On my desktop with nvidia pascal gpu, also X11, there is no such problems with popups.

I tried to disable all desktop effects about popups, but i does fix it.

I tried to disable all desktop effects about popups, <<but i does fix it.>>

sorry for the typo, It does not fix it.

Comment 7 Clementine 2023-07-30 06:04:54 UTC

I reinstall my system afresh without using thinkpad related acpi kernel modules.


It's fine now~
