+Subject: [PATCH] use GetWindow()->Refresh() in Wayland only
+
+Some people are reporting stuttering, and @retro-wertz tested both
+DrawArea() and Refresh() on wxgtk3 under xorg and found that the
+Refresh() method produces more stuttering.
+
+Change the compile check for wxgtk2 to a runtime check for wayland, and
+use Refresh() under Wayland only.
