Thumbnails when switching desktops

Is it possible to enable thumbnails for the “Desktop Layout Indicator” that shows up when switching desktops with shortcuts?

Is that a mockup or something? Looks very broken to me :joy: Oh sry you meant something else :innocent:

Yeah, it looks kinda broken, that’s why I’m asking.

I’m using Plasma 6.0.3 on Fedora 40.

Virtual Desktop settings:
Three rows with three desktops each (3x3)
:ballot_box_with_check: Show on-screen display when switching
:ballot_box_with_check: Show desktop layout

I would expect to see thumbnails, not that gray background without inner divisions.
