Testing in Ubuntu 15.04 (r168): This problem seems to be related to mir dropping old buffers when the visibility changes from occluded->exposed. If I remove the "drop old buffers" code from mir::scene::BasicSurface::set_visibility, then it seems to come right.
There have been some changes in mir related to the buffer stream and arbiter which I'm testing if might make a difference. It may also be that we're not handling the dropped buffers correctly in qtmir? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1514556 Title: With occlusion detection, apps stop responding when switching from another app. To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1514556/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
