1. Looks like preferences window is created as CSD window. This is not metacity bug - CSD windows are not decorated by metacity. This looks like problem also in Unity session... I would suggest to not use Ambiance theme with Flashback.
2. I can reproduce this in Ubuntu session, but I can not reproduce in my JHBuild session with metacity from current git master and gnome-3-18 branches... Might be ubuntu specific bug... 3. I can not fix this without clear steps how to reproduce. At least can you get stacktrace? -- 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/1557904 Title: 3 bugs from metacity 3.18.2 (for Ubuntu 16.04 xenial) Status in metacity package in Ubuntu: New Bug description: 1. Bug: Many Gtk3 Softwares don't show their border of window, based on Ubuntu Light-theme. (See attachment Bug1) sudo apt-get install gnome-session-flashback gnome-system-monitor gedit light-theme [Logout and login to Gnome Flashback Session (Metacity)] Open nautilus window browser, Open gnome-system-monitor, then open "Preference" item from menu. Open gedit, then open "Preference" item from menu. .. Non of these window have border, which is extremely unfit under metacity compositing mode (metacity -c --replace). Note: If I install an old version - metacity 3.14 (from Ubuntu 15.04 repository), it does have this problem. So it's metacity 3.18 that cause those border miss. 2. Bug: metacity are supposed to quit if a new window-manager replace it. Run: metacity -c --replace Then run: metacity -c --replace The previous metacity process doesn't quit, which both metacity 3.14 (from ubuntu vivid) and marco (from ubuntu xenial) doesn't happen. 3. Bug: https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1538111 This bug still not fixed. There is a small possiblity that closing a certain window will make all of other windows disappear, nothing would do anymore expect killing metacity and run metacity again. Then disappearred windows display again! I only found out that if I frequently plugin and plugout external screen monitor, the possiblity of getting stuck into this bug becomes larger, and "close a window" operation is key that might cause this bug.
