There's also a
youtube video(in spanish) that mentions the same issue. Had to google "koreader scroll" last week.
That's a bug but doesn't happen everywhere, so logs are very welcome.
FWIW I cannot reproduce with the exact same version and my desktop mouse.
Code:
sudo evtest /dev/input/by-id/usb-Logitech_G203_LIGHTSYNC_Gaming_Mouse_206D30754642-event-mouse
Input driver version is 1.0.1

Properties:
It produces the following event when scrolling with the mouse wheel
Code:
Event: time 1657011400.560990, type 2 (EV_REL), code 8 (REL_WHEEL), value -1
Event: time 1657011400.560990, type 2 (EV_REL), code 11 (REL_WHEEL_HI_RES), value -120
Event: time 1657011400.560990, -------------- SYN_REPORT ------------
A tricky bug, it seems. Hopefully easy to fix once we have proper crash logs.
