[SOLVED] KDE Task manager shows open applications as closed & pinned.

After yesterday's update, my task manager started to behave weirdly. When I open a pinned application, on the task manager it appears as if it never opened, if the program is not pinned, it will appear in the taskbar as if I just pinned it. The moment I close it, the program icon disappears. Interestingly, when I minimize the application the icon seems to behave as it should. It's kinda hard to explain, so I recorded a vid of it: https://imgur.com/jqa2QCb (I didn't find a way how to upload videos here, so I dropped it in Imgur.)

Troubleshooting steps I've tried:
- Reinstalling all the packages that I have touched in the last update
- Deleting and re-adding the icons only task manager
- Using an alternate task manager which also showed the same behavior

BTW: I updated my main computer yesterday too and unlike my laptop, it works correctly.

I'm running X11 on an integrated r7 5800H GPU.

Same. I fixed it by resetting the plasma to factory settings (deleting all its configuration files)

Ugh, this is something I want to avoid. What folders did you delete? I will probably back it up and then delete files one by one to find the offending one.

Also, I've tried searching KDE bug tracker and nothing seems to show up.

Re: [SOLVED] KDE Task manager shows open applications as closed & pinned.

Can you post your ~/.config/plasma-org.kde.plasma.desktop-appletsrc , respectively check whether it's screenmapping value is absurdely huge? There used to be some problem here with one of the glibc updates and how this config file was populated, you can likely try just moving that away/checking what happens if you remove garbage from the screenmapping value.

It seems to be reasonable, should I reset it?
[ScreenMapping]
itemsOnDisabledScreens=
screenMapping=desktop:/redacted.tar.gz,0,d05ef5bd-e818-4ab7-bd3d-00afc20b5e6c,desktop:/redacted,0,d05ef5bd-e818-4ab7-bd3d-00afc20b5e6c,desktop:/redacted,0,d05ef5bd-e818-4ab7-bd3d-00afc20b5e6c

Re: [SOLVED] KDE Task manager shows open applications as closed & pinned.

Looks ok, anything else looking wonky in there/can you fix it by temporarily moving it away, restarting plasma and repinning apps? The case I had in mind contained megabytes of garbage in the screenmapping value

Renaming the file seems to have no effect except it reset my task manager.

Re: [SOLVED] KDE Task manager shows open applications as closed & pinned.

Is this a visual or a behavioral bug? If xf86-video anything is installed try removing them and restarting. Maybe also post a system journal

sudo journalctl -b

I think visual? I'll try removing the packages. If with no success I will send the journal

Didn't help, here's the journal https://pastebin.com/06SRNgnh
Tried searching for KDE and didn't find anything interesting

Re: [SOLVED] KDE Task manager shows open applications as closed & pinned.

Not seeing anything obvious, what exactly was updated "yesterday"? Only candidate I have is the Qt 5.15.11 bump leading to some different visual behaviour.

Here's the pacman log, I've tried reinstalling all the KDE-related packages. https://pastebin.com/n3FKyuwE

I have encountered the same problem on my laptop. Also, I found that someone on Reddit also had the same problem ( https://www.reddit.com/r/linuxquestions … ndeavoros/ )

I just found this thread: https://forum.manjaro.org/t/kde-plasma- … r/149483/4

I logged out of GUI and deleted ~/.cache/plasma* . Now the problem is solved!!
