    The problem still occurs. Xiaomi Mi9, Android 9 (MIUI Global 10.2.30) and latest Unity 2019.2.13f1. New empty project, empty scene -> black screen when using Vulkan

    Error still happens. Making extensive use of ComputeBuffers so OpenGL 3.1+ is not an option.

    The device we found the issue to happen is an European Samsung Galaxy S9 with Mali G72 GPU.
