I have to say that I have given up using metacity for nearly two months because I encountered this issue all the time since using it and cannot find a way to reproduce it intentionally. Instead, I am using macro:yakkety which is also based on GTK3 and it works well and stablely.
I can confirm that metacity:trusty doesn't has this issue but metacity:xenial has this issue. And I can also confirm that metacity:xenial has this issue on virtualbox as well. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/1614050 Title: Window depth order messed up Status in metacity package in Ubuntu: Confirmed Bug description: Using the gome-flashback session with metacity is totally messed up since I updated from Ubuntu 14.04.3 to 16.04.1. All the effects mentioned here do not appear when using compiz, so I guess Metacity is broken. -Windows that should open in front (like Kupfer) appear behind the windows already open. -Before nemo is run, the Ubuntu default desktop background image appear, it can't be changed by settings. I just guess this is due wrong ordering of the true background and some window used by Gnome for showing the selected background. -If nemo is run to take over the desktop, the destkop icons appear in front of all windows. I guess all those effects originate from a similiar reason. None of these problems where appearant at Ubuntu 14.04. This is a total show stopper for using metacity on 16.04 as everyday applications like nemo and Kupfer can't be used.
