Re: [Linuxwacom-discuss] Intuos4 and pointer jitter

[Emil A. <emi...@gm...>]

Hi,
I have this small jitter with a Cintiq 21UX but it's not that apperent
when I use program that uses the "high-resolution" data like Gimp. The
jitter is all over the screen but only when it jumps between the
screen pixel boundaries.
I don't know that much about the windows driver but they maybe uses
some kind of reduction of the jitter for the pointer. it might be an
idea to add some kind of "sluggishness" that average the last 10 ms
position data to the xorg driver for the pointer.
Do anyone know how the windows driver solves this? Can we find out?
