+Subject: [PATCH] popover: Call unrealize on hide
+
+When popover is shown "realize" method is called which creates a new
+surface for popup. Unfortunately this causes performance drop on Wayland until that
+surface is destroyed what happens inside "unrealize" method during popover destruction.
+
+This commit changes default behavior in a way that surface will be destroyed
+when popover is closed and app will ragain the performance it lost when
+popover was shown.
