@Daniel: thanks for taking the time to file an upstream bug report. I have tested Maarten's latest work on the Qt library, and I can confirm that it solves the issue on both tablets and non-tablets. Maarten's work is available here (you only need to update the qt packages): https://launchpad.net/~canonical-x/+archive/x-staging

To reproduce: 1) On a desktop/laptop with a touchscreen (I am using a Dell XPS13), install 14.04 and check that the touchscreen works for moving windows 2) Install the camera-app package from universe (I have 2.9.1+14.04.20140331-0ubuntu1) 3) Launch the camera app 4) Touch once inside the camera-app window 5) Use the touchscreen to drag the camera-app window Expected results: You can move the camera-app window using the touchscreen Actual results: You cannot move the camera-app window, or perform any other touch tasks in unity, with the touchscreen This only affects touchscreen input - mouse/touchpad input is not affected This affects all apps written with the SDK (I tried camera-app, gallery-app, reminders-app). It's 100% reproducible.
