This issue was reproduced in X-IVAP and Altitude for X-Plane (IVAO clients): since the release of public beta 11.50, CSL aircrafts are not displayed in clients when Vulkan rendering is enabled. It works however correctly with OpenGL rendering.
Not a bug. Just plain, outright not supported in this tree (which I'm going to maintain for XP10 compatibility as long as practical). See xsquawkbox/xplanemp2 for my legacy-free path forward.
