>I've been playing around with fractional scaling in Wayland
Even with Intel graphics? I have stumbled on a number of showstopping bugs and moved back to X, which is also pretty horrible...
Oh, actually not yet. That's surprising as in general I think Intel graphics tend to have the best compatibility out there. Currently main workstation on amdgpu on a 5xxxG - I'm still not sure if I've gotten the hardware transcoding etc working properly but that's all unrelated to fractional scaling, I assume.
That aside, I've been playing around with fractional scaling in Wayland on everything from a 6" Pinephone to 32"@4k in various configurations and it's been mostly painless. Mostly terminal, web browsing, Steam games (latter not on the Pinephone obv). I wouldn't be surprised if there can be issues with xwayland that I'm yet to experience.
