Mouse weirdness with xinput Coordinate Transform Matrix

I have a mouse, which has DPI set to a constant 2400 on its board. I bring this down to ~700 with xinput, like so

xinput set-prop 8 "Coordinate Transformation Matrix" 0.3 0 0 0 0.3 0 0 0 1

This works fine for almost all cases, except World of Warcraft running through Valve's Proton (itself based on Wine). Here, the mouse tends to get caught in the top left corner, causing all sorts of issues.

Setting the matrix back to the identity fixes the issue. Does anyone know an alternative way of setting mouse sensitivity which I could try out? If not, does anyone know if evdev as my driver might offer an alternative (I'm currently using libinput)? Interested to know your thoughts.
