I totally support this.

Anyway we should make sure mutter lists the most important legacy modes
(like 800x600), regardless whether supported by the display or not, as
soon as it supports scaling.

Yeah I think it is. Actually the fact that things get scaled up in
fullscreen mode at all seems to be more of a side effect. I tried to
move the coordination fix into mutter, but once scaled up, the surface
didn't seem to have any reference to it's original size.

So that xwayland patch was just for tinkering around. With this xwayland
patch here, I'll look into implementing wp_viewport, which should handle
input and output scaling.


Thanks,
Robert
