Meta XR Simulator does not support OpenGL, while SDK does
Hello, I've tried to launch the hello_xr example from OpenXR-Source-SDK with OpenGL backend. There is the (shortened) output: $ XR_RUNTIME_JSON=/d/meta_xr_simulator/meta_openxr_simulator.json ./hello_xr.exe -G OpenGL [12:03:20.094][Info ] Press any key to shutdown...

Washed out (double gamma correction) on OpenGL
No matter which swapchain format I specify, my OpenGL application always renders washed out. That implies that OpenGL always thinks it is rendering to a linear render target, while OpenXR always thinks I am submitting an sRGB render target. Changing the swapchain format that I ask OpenXR to create between sRGB and linear makes no difference, and neither does glEnable(GL_FRAMEBUFFER_SRGB).3KViews1like4Comments
