I’m on nvidia, have 2 screens mixed resolutions and mixed framerates with kde plasma at the moment. I use jetbrains a lot which only really works through xwayland. I’ve tried every nvidia friendly DE there is and nothing ended up working consistently. I had been on wayland for more than a year on my previous Intel gpu machine but I had to go back now to x11 for stability and haven’t really had any issues ever since. Think whatever you wish but nvidia still has a large market share so until wayland works solidly with nvidia then lot of people will have issues with it. I imagine it works great on amd same as it does on Intel. (yes I know it’s debatably nvidia’s fault for this mess)
