Could it be checked if this got better with Qt 5.3 in utopic? There were
a lot of XInput2 / etc changes at least.

Title:
  Qt ignores input devices created after qmlscene has been launched

Bug description:
  (text extract from an email)
  We're having an interesting issue with the pinch touch gesture in autopilot that seems to be related to the recent upgrade of Qt.

  I've found that if I create a UInput device before launching qmlscene the pinch gesture works as expected, but if we create the UInput devices after it is launched no input is received in the sample qml app.
  So it appears that qmlscene is ignoring touch inputs from a device created after it is launched.
  This code was working with the previous version of Qt as well as works on Saucy.

  I have put together an example script[1] that has a pass and a fail
  test. The only difference in the passing test is that it creates a
  UInput device before launching qmlscene (commented in the code).

  To reproduce using this script (assuming autopilot is installed):
   - bzr branch lp:~veebers/+junk/pinch-gesture-failures && cd pinch-gesture-failures
   - autopilot run test_pinch_event.TestTouchEvent.test_will_fail
  or
   - autopilot run test_pinch_event.TestTouchEvent.test_will_pass
