@AlexRadacki Are you running Unity App in Windows PC and then connecting it with android web browser? Or running the App itself in android? Cause in Environment you mentioned Windows11.

Ah, sorry my bad - the platform is android of course. I've created an official Unity Bug Report for this issue. Here is what we found out already:

[...]
I’ve been able to reproduce the issue on a Pico 4E (OS: 5.12.0.S), which also comes with an Adreno 650. It works fine on a Pico 4UE (OS 5.14.4.U) though, which has an Adreno 740 inside.
Our Samsung Tab S7 with a 650 is running on OS: Android 13 (latest update)
[...]
Note: It is important that the only available graphics API is Vulkan, with no fallback OpenGLES: With that included, the app will run - without the Vulkan API, however. Our tech-art department informed me that Vulkan rendering is essential due to how z-fighting is handled on far-from-origin geometry.
[...]

So it seems that it only fails on Adreno 650 GPUs.

@AlexRadacki thanks for sharing the details.

I’m currently working on a similar project, I wanted to ask if you have tried running the Unity application on Windows/Linux with high end gpu and then streaming it to the Android device via WebRTC (e.g., through a browser)?

In our experience, this approach can be more stable and significantly reduces the load on the client device, especially when dealing with GPU-specific issues like the ones you’re seeing with the Adreno 650. It also avoids tight dependencies on Vulkan support across different Android hardware.
