This is what happens when the bug starts to show: On the Nexus 4, the edge drag areas are 36 pixels wide. When you do a left edge drag, the touch-press event hits the screen at x=45, so already past the left edge drag area (launcherDragArea), as this log snippet shows:
""" --------- EdgeDragAreas ------- EdgeDragArea_QMLTYPE_1_QML_248 "spreadDragArea" enabled=true visible=true sceneRect=QRectF(732,0 36x1280) EdgeDragArea_QMLTYPE_1 "launcherDragArea" enabled=true visible=true sceneRect=QRectF(0,0 36x1280) ------------------------------- ---------- Touch Pressed id=64 pos=(45.4704,547.286) ----------- """ Thus somehow the edges of the touch screen seem to get "numb" after some idle time... A simple fix (or workaround) would be to simply increase the thickness of the edge drag areas. This would have no side-effects as edge drag areas consume only edge-drag gestures. Taps near the edges would still reach the foreground app -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1408263 Title: Edge gestures still get lost To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1408263/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
