It was running fine before system upgrade.
Upgraded packages: pacupgraded.txt
I reverted updates to 2024.08.26 - everything started working.
Upgraded kernel and Nvidia stuff (Linux, linux-firmware, linux-firmware-whence, linux-headers, nvidia-dkms, nvidia-utils, lib32-nvidia-utils etc) - everything is working.
Upgraded everything else (it's very tedious, so I won't do bisection, or one by one)... And it's working now.
Idk what the issue was, but rolling back some dependency and upgrading it again fixed it.
