Please help us by

@Daniel: thanks for taking the time to file an upstream bug report.
I have tested Maarten's latest work on the Qt library, and I can confirm that
it solves the issue on both tablets and non-tablets. Maarten's work is
available here (you only need to update the qt packages):

Took the liberty of correcting the bug title as unity does keep getting
touch events. It's the xserver mouse pointer emulation from touch events
that breaks badly.

1- sudo restart lightdm (to restart the X server. so that de have a clean slate)

Is there a specific reason for calling XISelectEvents() for each slave

The code in Qt that subscribes to slave device events is the explicit
tablet-handling code. Checking the code, the touchscreen on my Dell XT2
is being treated as a tablet by the Qt code because it supports a stylus
mode on one of its alternate devices.
It sounds like the bug is in the Qt XCB QPA
Is there a specific reason for calling XISelectEvents() for each
slave vs using XIAllMasterDevices in QXcbConnection::xi2Select() in Qt?
Would have to dig into Qt code to tell that. But my guess is that
because it exposes QTouchDevice objects to applications. For every
QTouchEvent you can get
@Stephen: I guess that means that your device passes the following
check:
if (tabletData.valuatorInfo.contains(QXcbAtom::AbsX)
tabletData.valuatorInfo.contains(QXcbAtom::AbsY)
tabletData.valuatorInfo.contains(QXcbAtom::AbsPressure))
which you can check using xinput list-props
I've just rebuilt Qt with a partial fix which only covers the non-
tablet test case, and I'm glad to report that it solves the problem.
Maarten is working on an all comprehensive fix.
