When I try to move the cursor by a very small amount (a few pixels), by slowly rolling my finger, there is no movement at all until I’ve moved at least 50 pixels or so. Then the cursor jumps* those 50 pixels all at once. If I continue moving my finger slowly, I can make nice pixel-by-pixel movements, so the touchpad clearly supports the required precision. But the initial jump makes it very frustrating to point at small targets that are close to the initial cursor location. I always have to move the cursor away, then move it back, then adjust to hit the target without lifting my finger. I noticed the HorizHysteresis and VertHysteresis options, which default to 19 here, but reducing them has no effect. * This initial jump is animated, even, which is frankly just insulting. It’s as if somebody noticed already this bug and tried to cover it up by making it look like the user’s fault!
