Some debugging output from qtmir: http://pastebin.ubuntu.com/16387328/
qtmir.mir.input: Received MirPointerEvent(x=1175,y=915,relative_x=145.75,relative_y=0) qtmir.mir.input: Received MirPointerEvent(x=1243,y=915,relative_x=68.75,relative_y=0) qtmir.mir.input: Unrecognized pointer event qtmir.mir.input: Received MirPointerEvent(x=1181,y=1061,relative_x=-28.6186,relative_y=-2.60169) qtmir.mir.input: Unrecognized pointer event qtmir.mir.input: Received MirPointerEvent(x=1131,y=1058,relative_x=-78.1499,relative_y=-5.2086) qtmir.mir.input: Received MirPointerEvent(x=1084,y=1056,relative_x=-47.501,relative_y=-2.64137) The Unrecognized event must be "window leave", so USC thinking pointer left the unity8 window, so no more events are delivered. You can also see that while the "invisible edge" doesn't always happen on the same x (weird!), there has to be a negative x delta before any other event is delivered (but no "window enter" event ¿?). ** Also affects: unity-system-compositor (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580774 Title: mouse is getting stuck on a phantom edge To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580774/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
