screenshot

In the "icon only task manager" when I hover over an app that has an open window, and a preview is generated, an additional window "Plasmashell" "Plasma Workspace" spawns with an icon like an app.

Hovering over it reveals the empty plasma workspace background, leaving that hover area, the preview and icon disappear again.

I already tried a kwin window rule to remove the "app" from the takbar and overview but to no effect

All I see in journalctl is this
