Crosshair on sprite is slow [1.3-beta11-x64 mac)

with crosshair on sprite selected, moving the mouse quickly feels very slow and jittery. i thought my mouse was acting up but it was the same with my trackpad. after changing it to simple crosshair, it feels smooth and fast as expected. would it be possible to have a crosshair mode where above some speed it doesn’t try to quantize the position? i like being able to see the pixel i’m affecting more precisely but the slow movement really messes with me.
