Honestly it sounds like you suck more than linux does, because I have never had any of those problems. My 4k monitors have all worked perfectly, and with wayland i have a successful mixed resolution/scaling/refresh rate setup.
If anyone is being a bitch, its you. You sound salty as fuck. I kind of hope you don’t switch so the linux community doesnt have to put up with your awful attitude.
Oh, and no shit you need Proton. Thats not even worth discussing.
I think that talking about how you want to switch but then claim the thing you want to switch to sucks because of totally fabricated reasons is cringe.
I don’t think everyone should switch, but i do think that people walking around spouting out bullshit that they clearly have no idea about should be called out and shut down.
