Bug 2021.3.16f1 URP shaders doens't run on IPad Air 2

Hi,

We having an issue with our app on Ipad Air 2. We are building with 2021.3.16f1 using URP, but at start the screen goes black. Reading the log appears to be a GPU incompatibility.

We also got "get output frames failed, state 8196", I don't know if this is related.

How can we run on this device? Are there some player settings that can help?

This is the log:

Code (csharp):

1. Delete the library folder to get rid of any cache issues and try again
2. Try from a blank project to see if it's a unity issue or your project

 

I tried both deleting the library and with empty project. Same result.

Those are the steps:

- Open new project 2021.3.16f1 with 2D URP template
- Change the target SDK to simulator in player setting
- Put a TextMeshPro and a Sprite in the scene
- Build IOs with Debug and Developer Build

Run on any old device simulator like iPad Air 2 and you got the same message.

Does anyone have some ideas about that? Appear to be a GPU-compatibility issue.

Thanks.

 

1. Please make a bug report. Of the ios version is supported it should work
2. Not sure how to fix it sadly ):

 

Hi DevDunk, are you from Unity? (Just to understand if this is an official response).

Thanks

 

Nope, those will have a tag under their profile

 

Ok, before opening the issue, I hope from some feedback from the community, seam very strange that no one has noted that a common URP 2D project wants work on old iOS GPUs.

I note the same issue with iPad Pro 1° gen with 12.4 iOS.

 

If it happens in a fresh project, just report it so it can be looked at and fixed faster.

The official unity docs say it should work with ios 12+ and A7 SoC or newer:

Hi @Klamore74 did you try on a real device or simulator only ?
I actually have a game running with Unity 2021.3.16 and URP and I don't have any problem on real devices.
Maybe it's a simulator issue.

 

Sadly I have not any of this old device
