(Get the code!)
Found the problem!
Somewhere is the bespoke input logic for Unity8 we're assuming the device is (typically) around 100Hz so also generates large motion deltas. That's incorrect. My mouse is configured for 1000Hz so generates small (but many) deltas. You can test this with a sufficiently capable mouse using kernel parameter: usbhid.mousepoll=1.
Removing that kernel parameter fixes the speed. Although we should fix Unity8 because Xorg and Mir's demo servers don't have such problems with 1000Hz mice.
