Description

Hi, first of all — thanks for the amazing work on this library!
I’ve been testing the included examples, and they render perfectly on my main machine with an NVIDIA RTX 2070 SUPER.
However, on other systems, parts of the scene or individual meshes randomly flash to black or become invisible for a frame or two
No errors or warnings appear in the logs when this happens.
