Title: White flickering of Qt clients on Nexus 10 Status in Mir: Fix Released Status in qtubuntu package in Ubuntu: Fix Released Bug description: Nor sure if this a Qtubuntu bug or a Mir bug On a Nexus 10, do the following: 1. Download these files to the device: http://bazaar.launchpad.net/~unity-team/+junk/qpa-mirserver/view/head:/qml-demo-client/qml-demo-client.qml http://bazaar.launchpad.net/~unity-team/+junk/qpa-mirserver/view/head:/qml-demo-client/MovingRect.qml and place in the same directory 2. Run mir demo server by calling mir_demo_server_shell 3. Run qmlscene qml-demo-client.qml You'll see a blue screen with a short red bar animating from left to right. 4. With 3 fingers, start interacting with the new surface. Be vigorous, shake it around a good bit! After some time, I notice the white flashes in the blue surface - it seems like some frames are all white. QML is not doing that anyway. With more time, the flashing becomes more evident. I've attached a video showing the flashing here: http://people.canonical.com/~gerboland/mir-flicker.MOV The source of the whiteness does puzzle me. Could it be the Qt app misses the vsync, and an un-drawn buffer is used by the Mir compositor?
