So here's what's happening: If an application crashes, apport starts to trace it. This takes a couple of seconds delays the applicationRemoved logic until tracing is finished. During this timeframe the surface of the crashed app is already gone (or at least in a state where we can't screenshot it any more). If the user interacts with unity in a way where it requests a new screenshot (e.g. swiping from an edge) while in this state, it crashed unity too.
Alexandros has proposed a patch to just return an empty screenshot in this case. This works around the issue and just leaves us with a visual glitch (invisible surface floating around) until apport is done with tracing the app. This patch has been merged to the mwc demo ppa. So right now doing a mwc flash followed by a apt-get update && apt-get upgrade solves this for the MWC image. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1281728 Title: Unity8 random freeze on demo image To manage notifications about this bug go to: https://bugs.launchpad.net/unity8/+bug/1281728/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
