With GNOME 3.16 the developers are working hard at making their native Wayland support be rock-solid and reliable for day-to-day use for those wishing to abandon running their GNOME desktop on an X.Org Server. An important feature has finally landed for GTK+ applications in the Wayland world: the ability to minimize windows.

Armin K produced the latest patch to get GTK+ supporting window minimization with GDK's Wayland back-end. With the current state of affairs, the patch adding window minimize support for GTK+ apps on Wayland amounted to just a few lines of new code.

The Wayland minimize support is using the XDG surface API for handling the minimization work. The bug discussing GTK+ Wayland minimize support is Bug 695945 and was open since early 2015.
