GNOME Bugzilla – Bug 746935
Window shadow artifacts when popover shows outside parent window
Last modified: 2015-03-29 02:00:36 UTC
Opening a GtkPopover which subsequently displays outside the window will create artifacts from the window's shadow. Not sure if this is a mutter/gtk+ issue so feel free to reassign.
