Here is the problem.
I had been running X before last night. I switched to Wayland just before knocking off. When I started again today I was now running Wayland. I just now switched back to X and now my icon for kpat works properly.
Is there some issue with the Icons-Only Task Manager under Wayland?
I was going back to Wayland because it seems important Distros are dropping X. I should be running under Wayland because at some point I will have to. I am back on X for now.
Even for a home system? Not a fleet of data center servers. I am currently using rsync to backup /home/<>/ to the ssh server. I tend to make a lot of changes to the base Debian/KDE install.
