Nvidia really needs to get on Wayland already. I tried a few months ago to run KDE on Wayland+Nvidia it was literally unusable. I could not put a panel down without bugs. I'm running mixed DPI with the Nvidia driver and it's just easiest to make seperate X screens despite all the downsides that brings :/.

I'm going to be sad that a lot of little WMs are probably never going to make the jump. I'm not sure Wayland is ever going to get that many.
