I finally was able to reproduce it. Turns out it happens only once after system startup, if I log out of the session and log in again, the bug is gone.
Steps to reproduce: -Make sure no desktop file manager runs in the session (eg. remove it from the session / xdg autostart locations) -Start a gnome-flashback no effects session (Metacity) -Wait for the desktop (appears empty due to no file manager) -Run the 'nemo' file manager, set to overtake the desktop too -The file window appears, the desktop icons too, but the are in front of the window. -Close the window, the desktop appears to be normal -Open any other application, it appears behind the icons again. -Log out from the session -Start a gnome-flashback no effects session again -all is fine now. -- 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: New 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.
