--- Comment #3 from Peter Hutterer <peter.hutterer at who-t.net> ---
ok, there's one jump in there, shortly after the touch down.

initial x coordinate is 421 but in the third report it jumps to 556 and
continues normally from there. At the device's resolution of 12 that's a jump
of ~11mm and below the 20mm threshold we use to detect this. So this one would
trigger an actual jump, not just the error message.

This is garbage data from the kernel, to fix this we'd need some workaround.
Interestingly, the events that trigger the jump are less than 1ms apart. That
could be something that's detectable. is this a common pattern for these jumps?
