I’m guessing I didn’t build a component, but maybe it’s something else. I’m brand new to KDE Plasma development, so I don’t have a good intuition of what I did wrong.
Hi, did you try changing the window switcher to something else?
The default one in 5 was removed or replaced with a different one in 6, Thumbnail Grid, and it doesn’t fallback to a different one if you compiled Plasma yourself, last I checked.
KWin also moved from 2.0 to 3.0 during the transition to 6, which is what’s hinting me that you’re using the old window switcher. That, and the fact it’s looking for stuff in /usr/share instead of ~/kde.

And yes, I built everything intro ~/kde and used the script to install the session file. I do have Plasma 5 installed from Arch on the same system.
And yeah, the reference to /usr instead of ~/kde is indicative of files from plasma5 being used. I didn’t edit any system settings, so it may be using the plasma 5 switcher. I am not sure how to change that.
