Well, the clipping is required by design. That said, I agree using QML clipping there is not good enough and needs to be improved. Back then when the spread was implemented, MirSurfaceItem didn't support cropping yet, so this way of clipping had to be used.
The solution for this bug is to move to MirSurfaceItem's surface cropping mechanism and drop the QML based clipping. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1513047 Title: spread delegates are using clipping Status in unity8 package in Ubuntu: New Bug description: It appears that app windows are turning on clipping when the spread is opened. This is really inefficient graphically because it is a transformed rectangle and so Qt falls back to stencil-based clipping. We should avoid clipping in this case at all cost To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1513047/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
