This is solved well in Wayland, with X11 this is not as straight forward. Wayland comes with some other issues though.
Using solved and wayland i. the same sentence is just not right !

Wayland+Nvidia: Having it work sometimes under some conditions are not the same as solved. X11 is not flawless either but i feel it works more times under more conditions.
Ok rant over, sorry for sounding like a d*k :)
