Hi Bryan,
Thanks much for the testing.

I think this is an X server bug that was fixes a short while ago (it's in
the 1.7.5.901 release I pushed out today, search for "dix: don't update the
slave coordinates from the VCK"). Should be unrelated to the wacom driver,
unless you're seeing a completely different issue..

hmm. good question. Please run "xinput --test-xi2" and then move in a
circle. The raw events should look something like this:
EVENT type 17
device: 2
detail: 0
valuators:
0: 0.00 (-1.00)
1: -4.00 (-9.00)
where the two numbers are unaccelerated and accelerated values. Are they
always the same? if not, then acceleration kicks in and that's causing the
problem. If they are the same, it's the driver's fault.

out of interest - are all these bugs introduced by this latest patch set?
what was the last known working version? If you have one, can you git bisect
down to the patch that breaks it (or introduces one of these issues)?
Cheers,
Peter
