right. I got an AMD and the driver is utter shit. I had to disable features using kernel cmdline bitmask flags, so that it doesn't crash every 2 hours. wayland + amd classic.

never had compositor or display server issues with nvidia on linux.

    What GPU model is it? And what distro are you using?

    Did you install separate AMD drivers? You’re generally not supposed to do that; it’s just plug-and-play in the kernel and MESA (assuming the version is new enough), and you usually don’t need to download separate drivers.

    Also, what kernel flags did you have to use?

    It’s just that I’m a bit skeptical any of this is actually the fault of the AMD Linux kernel driver, and I would guess there’s some underlying software or hardware issue like a faulty ACPI implementation on the motherboard. I’m not saying AMD can do no wrong, but in this case, making blanket statements about the quality of AMD GPU drivers may be premature.

    rx 6650 xt, stock drivers that come with arch, amdgpu. issue is both on lts and latest. seems to be a ring buffer error. there's an open ticket about it.

    I don't remeber the flag, but it's to disable some power saving feature.

    That sounds more like something weird about the card itself than with the driver; "power saving feature" makes me think a faulty hardware ACPI implementation by the card vendor is to blame. I've had a similar thing happen with my Wi-Fi modem where it would completely crash and only a reboot would fix it; I too have to do special kernel options to get it working.
