ADDITIONAL INFORMATION

Comment 1 coding-matter 2022-07-26 12:02:28 UTC

Experienced this constantly on my desktop, but rarely experience on my laptop, maybe there is some problem of handling external keyboard.

Tried to change keyboard and it replicates.

Comment 2 coding-matter 2022-08-24 14:50:55 UTC

After switching to a Bluetooth mouse, it replicates every time when mouse (and computer) is idle for sometime (and it disconnects temporarily maybe for energy control). I guess that whenever a keyboard or mouse is disconnected and reconnected this setting is somehow forgotten or refreshed.

Comment 3 coding-matter 2022-09-20 00:31:29 UTC

This also happens when I use a bluetooth mouse and connect additional bluetooth device to it, e.g. earphone.

Comment 4 coding-matter 2022-11-17 18:07:29 UTC

I now am almost sure that the setting will be overridden or ignored whenever a new Bluetooth connection is started. It is strange because my keyboard is connected by cable.

Comment 5 coding-matter 2023-06-19 00:01:29 UTC

It seems to be fixed after switched to use wayland.

Comment 6 Andrey 2023-06-19 05:24:49 UTC

We have potential fix for that. Are you able to compile Plasma yourself to test it?
