iOS 11 Metal API issues with Unity3D 5.6.4f1 + vuforia 6.2.10.

iOS 11 Metal API issues with Unity3D 5.6.4f1 + vuforia 6.2.10.

We found iOS 11 Metal API issues with Unity3D 5.6.4f1 + vuforia 6.2.10.
We have a very simple ARCamera test app.
https://bitbucket.org/ARPlanet/testvuforiacamera.git
When we select Auto Graph API to build the application at Unity3D,
and execute the app in iOS 11 with iPhone 6s.
The screen record result is here

the iOS console message is here

We found that iOS 11 and Metal API will cause ARCamera to hang up and will display the following messages in the console
“Execution of the command buffer was aborted due to an error during execution. Discarded (victim of GPU error/recovery) (IOAF code 5)”

If we chose the OpenGL2 Graph API in Unity3D
The screen record result is here

the iOS console message is here

The results are very perfect.

I have similer issue.

my situation is as follows:

###Unity

5.6.2p4.

5.6.3f1

5.6.3p4

5.6.5f1

###Vuforia

6.2.10

##Graphics API

Metal

###Mobile

iPhone6 iOS 10.3.3

iPhone7 iOS 11.2.5 Beta6

iPhoneX iOS 11.2.1

###Result

iPhone6 : OK

iPhone7 : NG

iPhoneX : NG

Incidentally, it works on Unity 2017.1.1.f1.
But I need to satisfy the following conditions, I hope to solve this issue.

  • I use must ARKit, that is to say, I use must Unity 5.6.2 or more

  • I have pro lisence of Unity 5 so, I want use Unity 5.6.2 or 5.6.3

Is there a solution for this issue?
Or Is there plan to investigate and respond?

best regards.
