Wacom input jumps while drawing with xserver-xorg-core version 2:1.10.1-1ubuntu1.1
It is working correctly with version 2:1.10.1-1ubuntu1.
This issue is somehow related to issue #762938 (no pressure sensitivity with wacom tablet).
A fix for pressure sensitivity was proposed by Chase Douglas in the utouch-team/unstable ppa.
Using the official ubuntu Qt version, stylus position works fine, but pressure sensitivity does not work.
When using Chase Douglas's ppa, pressure works fine, but the cursor position jumps while drawing.
Note that the issue only happens when using the wacom stylus that is "pressure sensitive", not when using the wacom mouse that has no pressure.
As previously said, the "jumping cursor" issue disappears if I downgrade xserver-xorg-core to version 1.10.1-1ubuntu1

The bug can be seen in Krita, when drawing a line, the cursor jumps, a picture showing the problem can be seen here: /launchpadlibra rian.net/ 73690009/ Screenshot- unnamed [modified] – Krita.png
