The HelloWorld sample at https://www.lwjgl.org/guide (https://www.lwjgl.org/guide) tries to set the global window position.
// Center the window
glfwSetWindowPos(on
window,
(vidmode.width() - pWidth.get(0)) / 2,
(vidmode.height() - pHeight.get(0)) / 2
);
This is incompatible with Wayland as per GLFW documentation
