Bug / Crash 2 Rendering bugs on iOS(Metal)

[cliv3dev]

Hi there!

Thanks for taking the time to report this! I'm unable to reproduce this on an Phone Xs, iOS 17.6 using Obi 7.0.5 / Unity 2021.3.4f1. We usually develop on Mac using Metal then test in all other supported platforms, so it doesn't seem to be a Metal-specific issue (I'm not 100% sure there's any differences in the API that would affect mobile vs desktop, so there's still a chance Metal is the culprit).

Just to get it as close to your specs as possible, which iOS device are you trying this on? Will try to get my hands on something as close to what you're using as possible and get back to you.

kind regards,

Hola Jose,

it's an iphone SE 2nd gen so nothing fancy.
Just the OS and SDK version which are the latest versions and XCode is v16.2
You can find enclosed the log when executing from XCode...
After some frames without issues, Metal is not happy:
