It is related to the Samsung screen. There‘s a kde bug since Plasma 6.2 where this is happening. Long story short: disable ddc (look up your plasma-powerdevil.service file (mine was in /usr/lib/systemd/user) and add Environment="POWERDEVIL_NO_DDCUTIL=1" to it. Save, restart powerdevil (or reboot) and it shouldn‘t happen anymore.)
@tal@lemmy.today i found today 3-4 other persons having same or similar issues (one on the bugtracker github of systemd and 3 others on the archlinux forums) starting around the same time (in the last 2-3 weeks).
I dont think its Plasma related (which comes in later on boot I think) but maybe Kernel based - since others started having similar issue around the same time?
Might be related to some usb devices, but if i‘m not alone having it!?
