I mean it’s not surprising if theyre not actively trying to troubleshoot their problems. I run Linux on both my desktop and laptop and I never had a perfect experience with either. On my laptop a few years ago I tried installing Ubuntu but my trackpad sensitivity on linux was way too high with no easy way to change it. I also needed fractional scaling and at the time Ubuntu used X11, I found some command on the Ubuntu forums to enable scaling in the settings and it gave me screen tearing. After a few hours of playing around with different commands I gave up and weny back to Windows.
On my desktop I use Nvidia and have two monitors with different refresh rates. That causes a lot of issues and I just have to put up with it.
Edit: I use Arch on both of them now and have found solutions to my problems but especially my laptop issues were very annoying.
