Can you try again with the Plasma 5.21 beta? This is supposed to be fixed there

For Arch I should compile Plasma myself, right?
Can I also start a KDE Neon testing?

Oh Arch you can temporarily switch to the KDE unstable repo. See https://community.kde.org/Get_KDE_Software_on_Your_Linux_Distro#Arch_Linux
