This merge resquest has finally been merged into XWayland, which means NVIDIA users are just one beta driver release away (May 15th) from probably having a good experience on Wayland now!

Thank you for educating me on basic knowledge about WMs, which I use since ove a decade.

I just expect applications behave the same. I have literally not one single line of configuration for X11 in any of my configuration files.

I need this QT variable, otherwise Cura does not work properly.

Cura as in this one? :

Exactly. When the variable is unset the UI shows massive artifacts and weird rendering glitches.

I don't see any graphical glitches on my hardware.
Perhaps you're still on the qt5 version?
Maybe a bug with your Nvidia driver?
Perhaps your WM doesn't have explicit sync yet and your card & driver needs it in this particular case? Perhaps it's running under XWayland?

Wayland#Qt :
While it shouldn't be necessary, to explicitly run a Qt application with the Wayland plugin, use -platform wayland or QT_QPA_PLATFORM=wayland environment variable.

As it says above, it should really be inferred by default. Something weird is going on here.
