Sorry, I am not sure what is the right name for this: task switcher or task manager?
I am actually using the MediumDefault one.
Comment 2 Nate Graham 2022-09-22 21:08:53 UTC
It's a bug in the app itself, which does not specify its icon properly. GNOME works around this (with potentially other side effects), but in KDE we insist on correctness. :) I would recommend that you report this to Mozilla. Thakns!
