Intermittently, geometry does not appear and camera rot locks to Y
Describe the bug Intermittently (perhaps one or two runs in 20), geometry does not appear and camera rotation is locked to Y. Skybox and UI do appear, so I am thinking of a matrix..
To Reproduce I cannot recall if I have seen this in a sample, but my app is modeled after gltf_viewer fairly closely; I am loading a .gltf scene and flying around with ViewerGui.
Expected behavior The behavior of gltf_viewer.
Logs Nothing unusual is logged.
Desktop (please complete the following information): Arch Linux, GTX 1080, Vulkan
Additional context 'Sleeping drive' is eliminated as a cause. Samples using SDL2 seem to crash here on Wayland/XWayland, so I cannot test those at the moment. I have been seeing this one occur unchanged for several years now, with various IDEs and OS installs (certainly Linux, possibly MSW but not sure).
I suppose I can try to check matrices after discrete stages..
While it may seem unlikely that anyone else has encountered this, I thought worth asking.
