Public bug reported:
Situation:
Description: Ubuntu 18.04.3 LTS
Release: 18.04
Desktop: XFCE/Xubuntu
Installed HWE kernel 5.0 and HWE xserver.
Attached Wacom tablet "Bamboo Fun CTH-661" in "Relative" mode via xsetwacom
(behaves like a mouse instead of setting pointer to corresponding tablet
position on screen).
Issue:
When setting the pen down fast, the pointer skips notably, as far as 10cm on my
27" display.
Settings down softly it does occur, but the usual fast motion I apply
when using the tablet it occurs a lot.
It seems like in certain conditions, like going through the threshold at
which the tablet recognizes the pen the value changes too quickly an
overflown value goes into the X axis, but thata wild guess.
Reverting to all: regular 18.04 kernel, xserver and xinput-wacom drivers
the issue does not appear anymore.
Tablet has been working fine for years. HWE is first kernel/X/input
combo that jeopardizes it.
