1. The WiFi just would not work; I couldn't see any networks. 2. I have 2 monitors, and one monitor would display 80% of one screen, and 20% of the other. I suspect that it was because the monitors had different refresh rates and resolutions.
I then tried installing Windows, and everything did just work.
Especially speaking of playing games, I periodically see newcomer Linux gamers hitting problems due to Mint being outdated and not having good Wayland support. Especially for any kind of recent hardware.
KDE also started making its own Arch based distro now: https://kde.org/linux/
But it's one of those immutable flavors. I prefer something more flexible.
Personally I'm using Kinoite[1], an "immutable" version of Fedora that has an immutable base image, which makes it nearly impossible to break things during updates (even major upgrades).
With AMD, always make sure to use latest kernel, Mesa and amdgpu firmware.
But then there was a strange glitch on every single game (both native and Proton-based). Periodically (e.g. every ~10 seconds on some 3D games, on every screen reload on some other) the screen turned black for about 2 seconds.
Then I remembered that I had some issue when I first installed Debian 12 two years, though I forgot which issues exactly, and that I solved them by switching from Wayland to X11.
I'll try updating the firmware and drivers manually if I have more issues in the future, thanks.
If you like systemd, then I can offer no advice that will help you. :-)
Like, in regular Gnome/KDE land, you have Wayland which is a huge improvement over X11, HDR works, fractional scaling works... None of that works on Mint.
The former is Mint's specific problem, while the latter is a general problem of all long period release distros that don't take care of updating Linux kernel, Mesa and etc. to actual recent releases.
