Yesterday my system went through online upgrade from 7 to 8. Everything was smooth, after restart went to some updates and now is running fine, except that I cannot resize my plasma desktop icons. Were small before upgrade, now are big (48x48). I opened system preferences -> Icons, clicked on configure icons size, set desktop to 32, and the 22, apply, but nothing happens. Also tried changing theme from oxygen to brisa, but no luck.
uname -a
Linux localhost 5.10.33-desktop-1.mga8 #1 SMP Wed Apr 28 15:59:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
echo $XDG_CURRENT_DESKTOP
KDE
plasmashell --version
plasmashell 5.20.4
Everything else looks fine
