Bug Description

Sometimes it seems that subsequent touches in Libertine are interpreted as a linear mouse movement. I have a hard time describing this clearly with words, but I'll attach a screenshot showing the following reproduction:

Nexus 7, OTA 14
Install and run xournal in libertine
Tap on the screen and draw little circles on the screen : OK
Write 1 next to it
Tap on the red color in the toolbar
Tap somewhere and draw little red circles : NOT OK - it draws a straight line from where you tapped on red to where you've drawn the circles
Write 2 next to it : OK - now it does NOt draw a straight line
Tap on the file menu
Tap on the screen and circle : NOT OK
Write 3 : OK
Tap thick pen
Circles : NOT OK
4 : OK
Draw multiple little circles : OK
Write 5 : OK

I'm not really sure where the problem here is, but I'm pretty sure it's not Libertine in and of itself causing the issue.

My first suspicion is maybe Xmir is not doing something right, so I'll just add that task to this bug for completeness and mark the Libertine bug Invalid.
