I did some investigation since my last thread, and noticed that on Windows, my iCUE commander pro disconnects and reconnects every so often. I searched for this problem online, and it seems to be a known issue for years.
So I suspected this might be what is causing problems on Manjaro, so I tried monitoring the usb events using sudo dmesg -w | grep usb, but this problem does not seem to happen here.

Another thing that I noticed is that my steam client freezes for a few seconds sometimes as well. But I don’t know if it is related. The steam logs of when a freeze happens do not provide any insight on the matter.
