FWIW, gkrellm wasn't flexible enough for me so I'm now using conky with
custom lua-scripted reporting (ultimately ported from superkaramba, RIP!),
but with gkrellm back then and conky now, both, I'm still using window
rules to great success.
What I'm wondering, however, is if your upgrade to Fedora 34 switched kde-
plasma to wayland-by-default. I'm on wayland exclusively now (xorg isn't
even installed any longer), but back when I switched from xorg to wayland,
I had to redo a *LOT* of window rules, changing the window-matching
criteria to that of wayland -- basically window roles disappeared, and
window classes changed, so most of my old rules no longer matched when
running on wayland.
Depending on the versions you are running (I run kde-frameworks and plasma
live-git-master, so always the pre-release newest), however, for a time
some of the window rules simply didn't work at all on wayland, even when
they matched correctly. They generally work now, but some of the behavior
is slightly different, and some things (which screen, for multi-screen
setups, for instance, with a workaround of absolute whole-desktop position
coordinates instead of screen) were broken entirely for awhile and only
recently fixed, so if your version isn't new enough...
In any case, unless you go like I did and eventually uninstall xorg, you
should be able to have both wayland and xorg, and should be able to choose
either type of session, as desired. (If you're like me and do a CLI
login, starting kde from there, you choose the session to run there
instead of via *DM graphical login, but AFAIK most *DMs will have entries
for both, if you do the graphical login thing.)
