Hey, on relatively simple scenes cycles on metal has been performing pretty great. but when I start using on some more complex shots with linked libraries with overrides, view layers, and AOVs, I frequently run into issues where things suddenly will stop rendering or the entire system will lock up. the console reports a variety of issues, some of which specifically mention cycles metal (attached screenshots).
its hard to troubleshoot what is causing it, since it can render find one moment, and then the next it fails. and then render fine after a restart.
