Thumbnail grid task switcher doesn't higlight selected program

I’m facing an annoyance with the task switcher in kde plasma 5.27.10 on Manjaro 23… Even though the thumbnail grid shows all programs quite nicely, it doesn’t highlight the currently selected program’s thumbnail, so it is pretty much impossible to tell which program is being selected without having to look at the windows in the background behind the thumbnail grid. That totally defeats the purpose of having the thumbnail grid in the first place.
Any plans for improving this ? Didn’t want to post it as a bug on the KDE website, so I’m posting it here.

It does, atleast on Plasma 6. Should probably also on Plasma 5 but I can’t remember.

This sounds like a cache bug. See if moving aside or deleting the contents of ~/.cache/ fixes it.
