The Window Switcher installation is broken, resources are missing

I updated my sytsem and now when alt-tabbing twice (to get the task selector to appear) I get the following error in a kdialog notification

"The Window Switcher installation is broken, resources are missing
Contact your distribution about this."

This is a stock artix system that I hadn't updated for a month or so until now

Have you changed themes at all ?
Anyway in system settings
Workspace > Window Management > Task Switcher
there is a stupidly unlabelled dropdown (under "show selected window") which sets the task switcher theme.

Mine says 'Breeze'. What is yours set to ?

Play around with changing it. There's a preview button next to it.
Try changing it back.

TLDR:
Something to do with your theme most likely.

Mine is set to "Breeze" and I've tried a few others, but without any change. Changing my system theme also doesn't seem to have an effect on the task switcher error

Try opening konsole and
Code: [Select]
pkill plasmashell && plasmashell

Let the messages settle down then alt-tab and post the new output.
Might tell us something. Might not ?

Be warned that if you close that konsole window plasmashell will be killed again. It might be worth logging in and out if you think you could get stuck (Can start again with krunner though. Test Alt-F2).

I left my other account credentials at work. I have a similar system at home and also updated, which was dumb, as now I have the same error here. Killing and restarting plasmashell didn't work. Alt-tabbing twice again gave the same error. I haven't tried rebooting yet, that's a bit of a hassle and should be unnecessary for a Linux workstation.

I wish kde would tell us what resources were missing.

The purpose to killing and restarting plasmashell, in a terminal, was to see if there would be any useful error messages in the terminal output?

There was nothing output when I'd alt tab, but on startup I saw:

"QApplication: invalid style override 'gtk' passed, ignoring it.
    Available Styles:Breeze, bb10dark, ..."

"Gtk-WARNING **: ... Unable to locate theme engine in module_path: "adwaita",
"Gtk-WARNING **: ... Unable to locate theme engine in module_path: "adwaita"

I checked all the theme settings I could find and didn't see adwaita selected anywhere. Especially not for the task switcher

It was a long shot but worth a try.

If I was having your issue the next thing I'd try would be creating a new user
Code: [Select]
sudo useradd -m test1
sudo passwd test1
and logging into the desktop with that user.
Oh before you do that get rid of any kde settings that may have been copied from /etc/skel
Just leave /home/test1/.bash_profile & /home/test1/.bashrc

If you log in as test1 and ALT-TAB switching works you have a problem with your user config files in ~/
If it still doesn't work there's a problem with the system files.

I'd suspect the former as it's working for me.

I made a new user and didn't see the problem, but went back to my original one and also didn't. I think perhaps logging out and in (or changing themes, then logging out and logging in) fixed it. Thanks
