Do you see this problem when you turn off compositing manager and restart program? All your mentioned programs are CSD windows and I think GTK+ does not support toggling compositing mode - you need to restart program.
If you have same problem after restarting application then problem might be in theme you use. For example it might miss .solid-csd styling that is used when application is used without compositing manager. In short this is not metacity bug. -- 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/1516323 Title: With compositing off some apps have a huge black border Status in metacity package in Ubuntu: New Bug description: In Xenial I notice with compositing switched off several apps (nautilus, gedit, totem, gnome-tweak-tool, system-monitor & empathy) have a huge black border as shown in the attached screenshot.
