Module

Bug description

I tried running the HelloOpenXRGL on linux with LWJGL 3.3.5 but there are 2 problems with it.

1. you need to add GL21.GL_SRGB8 to the desiredSwapchainFormats at line 600-603
2. The real problem I see though is that the 2D window the sample opens is empty on X11 and not even showing the window border on wayland.

Im running Gentoo Linux with GLFW 3.4

It has been a long time since I wrote this sample, and I don't really use OpenGL nowadays. Could you elaborate point (1)? Why is it a good idea to add this desired swapchain format?

Regarding point (2), that is desired! I never wanted to create a window; I just want to render on the headset. But... creating an OpenGL context without creating a window is surprisingly hard, so the easiest way to do this, is by creating a small invisible window.
