I'm not sure what else should I put in here
Hi makabaka, I see this is running on a simulator device. It seems the simulator does not currently support MSAA depth resolves, although the physical iPhone 12 does indeed have support for this feature. SceneKit also seems to not correctly check if the simulator supports the feature. I would expect it to disable MSAA on devices that do not support it.
Please file a bug report using Feedback Assistant, provide your device configuration and if possible an xcode project that reproduces the error, then post the FB number back here so I can see it. I can then escalate the issue to the appropiate channels to resolve it.
In the mean-time, when using a simulator you can set the antialiasingMode of your SCNView to SCNAntialiasingModeNone;
scnView.antialiasingMode = (
#if TARGET_OS_SIMULATOR
SCNAntialiasingModeNone
#else
// whatever anti-aliasing mode for physical device
#endif
);
or the equivalent of swift with #if targetEnvironment(simulator)
