This is caused by the most recent mir/unity-mir landing. From the video above it's not that the initial input didn't get to the shell and the app wasn't closed, but in fact it's the last few frames that were not delivered to the display, resulting in you thinking that you're tapping on the close button, when in fact you're tapping on the browser icon.
This can be observed in a few ways: - after tapping close on an app, leave it be for a few seconds and see that nothing happens until you touch the screen anywhere (e.g. start scrolling) - after unlocking, wait for the infographics animation to stop, give it a few seconds and touch the screen - at which point the last few items in the infographic will show up again ** Summary changed: - touch input for close app in running apps scope sometimes results in browser launching + Rendering/composition gets stopped early ** Also affects: unity-mir (Ubuntu) Importance: Undecided Status: New ** Also affects: mir (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/1293896 Title: Rendering/composition gets stopped early To manage notifications about this bug go to: https://bugs.launchpad.net/unity8/+bug/1293896/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
