The main issue I've noticed isn't so much that you can't get the acceleration speed (which you can seem to on whatever display is being scaled to with HiDPI, though...

@0000matteo0000 @j9ac9k ohhh this is super cool! I would like to get this feature sooner then later. I'll see what I can do about testing some of my own use...
