I have an X1 Carbon 7th gen with a 4k screen (3840x2160). I run it at 2x scaling on Wayland (sway) and I haven't had any issues with native Wayland apps. X apps are rendered at 1x and upscaled, making them blocky or blurry. Apparently there are some apps like Spotify that ignore scaling settings and always render at 1x, but I haven't run into them. There is a fix in progress for XWayland scaling: https://github.com/swaywm/wlroots/pull/2064 https://github.com/swaywm/wlroots/pull/2064
