> At least with Sway, I had trouble getting anything with X11 working, particularly anything involve "pop ups". That includes right-click menus and stuff like that. Wayland works much better.

? Sway is a Wayland compositor

I use it as my desktop environment. I was using XWayland at first to get this working since that was historically the norm with Wine stuff, but that ended up being really glitchy. The latest versions of Wine/Proton actually have native Wayland support though so once I forced that it ran significantly better.

I don't know if this is an XWayland problem, or a problem with X in general, since I don't have any computers running X anymore.
