Looks like unity/compiz adds their own decorations also for CSD windows... Metacity does not do that and is should not do that - CSD windows are supposed to have their own shadows, borders and resize cursor area. Just because unity does that does not mean that there is bug in Metacity.
As you already know - Adwaita theme does work. So it is theme problem... But Ambiance theme can not be fixed... Ok, it can, but it will create problems for Unity session. And I am quite sure that Adwaita theme is not only theme that works. Any theme that have popper support for CSD windows will work. --- Are metacity only downgraded application? Is 'metacity --replace' problem reproducable in clean install? Dmitry, could this be regression after multiarchify library? Could it be build differently that triggers this bug? I see also this warning: Window manager warning: Log level 8: g_main_loop_is_running: assertion 'loop != NULL' failed --- Screenshot does not help me. I need reproducible steps with how to trigger this bug. In other bug you wrote that you can reproduce in virtualbox. I asked for steps that could lead to bug... Also if metacity crashes for you - then please try to get stacktrace. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/1557904 Title: 3 bugs from metacity 3.18.2 (for Ubuntu 16.04 xenial) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1557904/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
