well, cinnamon works great on mint and fedora, and i have had less (none) gpu related issues on mint than i did even on windows. kde wouldn’t play nice with my old pc components either and gpu is the only thing that i kept, so i would suspect it’s some weirdness between my gpu and kde.
and too bad i can’t go with amd because i need hdmi 2.1
<1080p screens are still a thing in new laptops. took a quick look at my local electronics store and found some with 1600x900. but most are indeed at least fhd.
