What happens with Wayland?

SUMMARY
The layout indicator in KDE (apparently) randomly disappears from the panel under unknown conditions. Layout switching still works, though.
I don't change any settings, but the problem persists.
Sometimes i just notice it's gone, and to return it i need to change locale settings. For example, switching "OSD on layout change" option on/off returns the indicator.
I tried:
1. Installing a flatpak version of Telegram (it could be the culprit, but it wasn't)
2. Setting options of the tray to always display the indicator (was set to "show when relevant"), nothing changed

OBSERVED RESULT
The keyboard indicator randomly disappears from the system tray (completely).

EXPECTED RESULT
Should be always shown when it's set to.

It still doesn't answer the question? ^

> What happens with Wayland?

I don't use it. I tried to switch, but encountered a bunch of problems i don't have on X11 or had fixed them.
Also, the bug started to show up even before i've switched to Arch (was Manjaro, previously). 1.5 month in total, approximately.
Comment 6 Andrey 2023-06-07 08:38:24 UTC
Can you try to reproduce on Wayland at least? It's important to further investigation.
Comment 7 Foresteam 2023-06-07 09:41:54 UTC
I'll try to, but i can't even reliably reproduce it on X11. As i said, it occurs randomly.
I also just noticed that "OSD on layout change" was doing nothing on X11 (excluding "fixing" the layout indicator) while on wayland it actually shows an OSD. Mb it's somehow related.
Also, i had completely wiped system files and configs during my switch to Arch, but left user folders untouched. So it may be related to my user space itself.
Comment 8 Nate Graham 2023-06-07 18:49:38 UTC
Is the screenshot showing the right thing? It doesn't appear to show anything from Plasma.

Comment 10 Andrey 2023-06-08 08:03:50 UTC
Can it be somehow related to your USB/Bluetooth keyboard become reattached or something like this?
Comment 11 Andrey 2023-06-08 10:19:50 UTC
Try also to find correlation with this lines in the log when it happens:

Also, as a quick hack, try to comment out this line in the .qml file and see if it helps (restart Plasma after that):
        Plasmoid.status: hasMultipleKeyboardLayouts ? PlasmaCore.Types.ActiveStatus : PlasmaCore.Types.HiddenStatus

My PC has no Bluetooth. The only USB device i periodically reattach is my webcam.
Comment 14 Andrey 2023-06-14 04:52:05 UTC
That webcam actually might be the reason, we have related fix which wasn't merged.
Could you retest without it?

This seems to have solved it. Or at least i didn't notice it happen again. Now the indicator "freezes", showing the wrong layout until i press the switch combination again.
Some software has been updated through this time, though:
* Linux 6.1.33-1-lts
* KDE Plasma Version: 5.27.5
* KDE Frameworks Version: 5.107.0
* Qt Version: 5.15.10
Comment 16 Andrey 2023-06-16 10:26:54 UTC
So it "fixes" a symptom and not the reason.
For the reason, patch I mentioned above might be useful.
But first I wish you test without the webcam or other auxiliary USB devices.

Not "fixes", actually. A few hours ago it stuck completely and i had to use that checkbox in settings again.

It's indeed probably related to the webcam. As i plug it in, i sometimes notice the bug in an hour or less.

Immediately, actually.
