I see.
Would it be fair to qualify the last statement by adding "in this use
case"?
Only if someone can report an Nvidia GPU being used under Wayland. Note
that this is not a KDE/Plasma issue. I get the same results under
Gnome. Note that I'm using SDDM in all cases. I don't know if that
makes a difference though I don't see why it should.
Is is possible to test this with the nvidia device being Default?
I think that would mean blacklisting the IGP on boot, if that's even
possible. I don't know another way of selecting the default.
Is it possible to test with nouveau instead of nvidia drivers?
Probably. I'll look into it.
