This is not really an hyperlap bug, but it's related to windows and LWJGL3. When you minimize the window GLFW fires a resize event with width and height = 0. This may cause additional problem in future, so I think that the best solution is to avoid call SceneLoader#resize when width or height are 0 (this is also good for performance because scene loader recreate FBOs when you call resieze).
