Issues
Backlight
Screen backlight brightness is always at maximum after the startup. The problem is that systemd-backlight@backlight:amdgpu_bl0.service reads the value (saving it before the shutdown) from the /sys/class/backlight/amdgpu_bl0/actual_brightness, which seems to be stuck at some value (249).
Manual adjustment could be done by by writing 0..255 to /sys/class/backlight/amdgpu_bl0/brightness (or by using, for example, brightnessctl). Reading from there produces the correct value as well.
Possible workaround is to write preferred value to /var/lib/systemd/backlight/pci-0000:00:01.0:backlight:amdgpu_bl0 and make it immutable with chattr.
Seems like the same issue as the one mentioned in the comment 19 of this kernel bug report.
Wi-Fi
Wi-Fi seems to be unstable (crashes often, losing connection).

- The key is visible to
xevand similar tools - The physical key has a symbol on it, which describes its function
- systemd handles this by default
