Piszę bo może ktoś jeszcze ma problem z lagującą myszą w “dużych” środowiskach graficznych i szuka rozwiązania. U mnie były częste mikroprzycinki, a w logu wtedy pojawiało się mniej więcej coś takiego:

Stało się to po zmianie karty graficznej (RX 5700XT na RX 6900XT). Po małym śledztwie okazało się, że winne jest libinput. Zmieniłem libinput na evdev i wszystko teraz śmiga gładko bez przycinek. Wystarczy:
cp /usr/share/X11/xorg.conf.d/10-evdev.conf /etc/X11/xorg.conf.d/
no i restart DM.
