Hello, currently our game isn't working on the iPhone 8. After a short time playing the game (few seconds to a minute), the game freezes and the device log shows this error messages: Execution of the command buffer was aborted due to an error during execution. Caused GPU Hang Error (IOAF code 3) Execution of the command buffer was aborted due to an error during execution. Ignored (for causing prior/excessive GPU errors) (IOAF code 4) The last message (with IOAF code 4) is then produces infinitely. As we use command buffer to draw some meshes, the first step for me was to totally disable all command buffers. But even with all our command buffers disabled, the game freezes with the same error messages. I double checked it by displaying the commandBufferCount of the camera which was zero all the time while testing. Our game is currently in the app store using Unity 5.5.4p3 and has this error. But we are internaly updated to Unity 2017.2.0f3 and also 2017.3.0b4, but both produce the same error. We couldn't reproduce this problem on iOS Devices with older GPUs. So e.g. the iPhone 7 is working without any problems. Do you have any suggestions what I could test for further investigation?
