Unsupported extended range format

Porting a project to an unbounded app, testing on simulator only.
Xcode compiles OK, but I get a crash on loading.

*** Terminating app due to uncaught exception ‘CAMetalLayerInvalid’, reason: ‘unsupported extended range format’

In CreateSystemRenderingSurfaceMTL

surface->layer.pixelFormat = colorFormat; - Thread 1: “Unsupported extended range format”

Any ideas?

Hello, thank you for flagging. We’ll need some additional information to be able to reproduce this issue. Would you be able to raise a bug in the meantime with relevant details about your project?

@IsaacsUnity turns out, this was a color gamut issue, with more details here.
