Created attachment 416784 [details] Add missing gtk/gtk.h include to PointerLockManagerX11.cpp In certain configurations, with GTK3, WebKitGTK fails to compile due to header gtk/gtk.h not being included in ./Source/WebKit/UIProcess/gtk/PointerLockManagerX11.cpp. I think disabling OpenGL was the trigger, but don't recall exactly. See attached patch.
