--- Comment #9 from Robert <freedesktop at postfach.xyz> ---
Thanks Andrew, but I guess I don't know how to interpret your last comment ;-)
Is there something I can test/change? I can't change the value of
"/sys/class/drm/card0/device/pp_dpm_mclk" which is the memclock frequency
AFAIK. It always stays at 875Mhz regardless which value I submit. As soon as I
start KDE Plasma I open "konsole" and I see the 875Mhz. So the power usage is
already high at this point and not after using KDE Plasma for a while.
Executing 

echo "2" > /sys/class/drm/card0/device/pp_dpm_mclk

e.g. doesn't change the freqency.

Maybe it's a "KDE Plasma + X server" thingy. Users which are using "KDE Plasma
+ Wayland" seems less frequently affected by the problem. But that's not really
an option for me as I need screen sharing from time to time via Zoom video
conferencing or Slack and AFAIK that still doesn't work with Wayland (besides
other problems). It's somehow funny that Wayland seems to be less of an issue
than X...

Maybe it's a X570 chipset + 5700XT thingy. I've no idea. I'm not a driver
developer ;-) I can only try things out like settings or patches (if I get
some). But I guess this is one of the issues that some future commit will maybe
fix "by accident" or it will just stay there forever ;-) If I see how long
other AMD related threads stay around in this bug tracker without solution or
some solution after years I currently don't have much hope that there will be
any solution for my problem. Hopefully Intel launches a dedicated graphics card
sometimes next year. I never had notable issues with Intel hardware and Linux
within the last few years. It just works ;-)
