If you could capture a trace of the issue in renderdoc or apitrace [1] upload
it somewhere and provide the link we might be able to investigate it. But
currently I can't get a trace because the HashLink virtual machine crashes.
Maybe you guys could try compiling with HL/C and try grabbing a trace with the
binary?
