I have tried a Wayland Gnome and Plasma session, in both cases the render
stutter of Oblivion and the "mouse blocking" of Hitman 2 are gone.

But: As I have stated earlier, this can also be achieved on Xorg with Xfce's
xfwm  and kwin-lowlatency (a KWin fork with different vsync implementation)
compositing. They also trigger pageflipping and thus achieve a tearig free
I would guess that having that extra vsync + extra backbuffer queue of a
compositor can avoid that "collision" of pageflipping + mouse input, in which
case we can't be sure if Wayland really isn't affected.
