Wayland now works great with Nvidia! Just two issues I am facing - some websites (such as Miro) lag a lot when moving around the canvas, and Chrome has some funniness where the window appears a few centimetres from the top of the screen, causing me to click the wrong buttons. The latter is fixed by un-maximising and maximising the window a few times
I was one of those people who Wayland Nvidia was unusable, with text lagging in text and code apps, the mouse feeling slow and constant flickering
