Shadergraph blackboard variables broken on Android

[olejuer]

When compiling a shadergraph for Android, the variables in the blackboard are broken. It seems they are interchanged, as if their indices got messed up. The same shadergraph will work just fine on screen and in builds for Windows. Can only be reproduced by compiling an apk and testing on the device, using a shader that makes use of several blackboard variables.

This might be related to other issues with shadergraph 7.1.6 on the Oculus Quest, such as materials not appearing at all ( URP shader graph material objects don't appear on Oculus Quest )

Anybody an idea of how to fix this? Seems like cannot do much except hope for fixes by Unity.

Reproduced with
Unity 2019.3.0f1
URP 7.1.6
Google Pixel 3 & Oculus Quest (Oculus Integration 1.43)

Here is a screenshot of the shader in a minimal variant that produces the error. It renders a hole between the camera and the character to have it always visible. It works on HTC Vive and on screen. It used to work on Quest, too, before Unity 2019.3. Now, it just renders black and the clipping is at seemingly random positions. If the variables are replaces with constants, it works as expected. So it must have something to do with accessing blackboard variables on the Oculus Quest.

I received an email saying that this issue will be fixed with the upcoming 2020.1.0a19
