graphics/sound stutters

Hello there.
Okay, so - sometimes (often, but short-lasting) I get stutters.
The graphics and sound seem to pause for like 0.5-1 seconds.
This is very noticable in MPV, while playing something.
And I think that it also happens outside of MPV, but isn't as noticable? I
might be wrong there.

GPU:
AMD RX 5600XT 6GB OC

Drivers:
drm-54-kmod-5.4.191_1          DRM drivers modules
gpu-firmware-amd-kmod-navi10-20220511 Firmware modules for navi10 AMD GPUs

Anything else I can help with? Perhaps a dmesg output or otherwise?
