As of mid 2021, FlightGear is in the process of working towards adopting the OpenGL Core Profile, this means that [[PUI]] is causing trouble and needs to be replaced/disabled or ported. | ||

FlightGear uses a GUI widget set that is implemented on top of [[OpenGL]]. This has many advantages from a portability standpoint and from the standpoint of integrating with window systems. [[PUI]] doesn't have every feature under the sun, but it was never meant to. It's relatively small, lean, mean, and written on top of [[OpenGL]] which makes life *much* easier for us. | FlightGear uses a GUI widget set that is implemented on top of [[OpenGL]].
