It's just general polish. Like I was daily driving fedora last year and :
- fractional scaling did not work in Gnome with Wayland for X11 Apps
- I still cannot use my LG C4 as a monitor in full capacity because AMD on Linux does not support HDMI 2.1
- Screen sharing was very buggy - in Slack especially - it would constantly crash the slack app during calls, ditto for camera, but even in Google meet and Chrome I've had desktop crashes
- When I switched to KDE/Plasma 5 to get fractional scaling it was extremely unstable
- Right now I upgraded my GPU to 9070XT - I'm still not sure if that would work on Linux yet because of driver support delay
- Guitar Amp simulator software I use does not support Linux, neither does Ableton (which supposedly can run on proton but with many glitches)
- The audio DAW situation was way too complicated and buggy
- I spent days to get the distro functional and usable with Ardour and it would still crash constantly - I just wanted to run some amp sims :(
It's just the little things and rough edges, but for example the fractional scaling stuff already improved because more apps that I use added Wayland support. And the emulation is getting better, with more users I could see larger DAWs supporting Linux as well. Not sure about the audio progress - JACK was a complete mess.
