The problem does not occur in a Gnome Flashback (Compiz) session, so it is evidently a result of the interaction between the XInput2 touch grabs used in Unity 7 (through Geis), the passive Xinput touch subscriptions in Qt, and the pointer emulation in x.org.
Multi-touch pointer emulation in XInput2 is documented as acting the way as described in this bug when multi-touch sequences are neither accepted nor rejected (ie pointer emulation stops when the first touch ends - see http://who-t.blogspot.ca/2011/12/multitouch-in-x-pointer-emulation.html) although it is unclear why the emulation does not resume when all touches have stopped. It sounds like the Unity touch support needs to add gesture accept/reject. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1307701 Title: Unity does not get touch events when QML apps running To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1307701/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
