I experienced the problem after I finally did a major update. Maybe it is a udev vs evdev thing.
I do not have this probem on MX (you know, the old Mepis / Antix related distro).
Funny thing is I cannot find xsettings or something there. If only I would know where to look I could compare :)
There is a EXEGNU LiveCD with Trinity, if I recall correctly it is working well there.
xinput (find you mouse) xinput list-props ID and then use xinput set-prop to set relevant ones
xinput --set-prop ID 'libinput Accel Profile Enabled' 0, 1 will set unaccelerated profile which you probably want on high dpi mouse and if it still too fast, play with 'libinput Accel Speed'. f.e -0.5 will set it to half, etc
P.S. It is possible that you mouse DPI is not detected properly by driver use ls -l /dev/input/by-id/ to find you mouse, then udevadm info /dev/input/eventX | grep MOUSE_DPI if its not set, use mouse-dpi-tool to find actual dpi and create /etc/udev/hwdb.d/71-mouse.hwdb with values from it
