By a strange coincidence, I just found a fourth bug, and I'm sure I've never seen this before. I started /usr/bin/mplayer from commandline, which opened a window (with default -vo setting), and it became listed as a window of /usr/bin/firefox in both Alt+Tab and Dock. It didn't happen again. You will probably not be able to reproduce it easily (I've never seen this despite doing this over 1000 times since I first installed Unity), but that's normal, that's the case of many race- conditions, and this looks like one. There is often no other solution than just reading source code to make sure it does no mistake about locking or atomicity (whatever happens to be needed in that area of the code).
In contrast, the second and third bugs (see description above) have happened systematically for years. For the first bug, I don't know, it's harder to notice. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1673072 Title: Open apps (even basic system ones) can still be missing from Alt+Tab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1673072/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
