Note:
- The graphic may break on some versions since this is a very specific case
- Looks like it is Mali specific issue
- Could not reproduce on Vulkan
- On GLES it seems that there is a clear difference between mali and Adreno devices, but on Vulkan, it seems that some devices have a white screen, and other display the same as in the editor
- Images attached "WithVulkan.png" and "Expected.png"
- No repro on iOS

Resolution Note (2021.2.X):
The project needs to use bindMS also for the color attachment when using OpenGL ES.
The issue on very old Vulkan drivers on Mali is most likely a driver bug. We don't support those drivers anymore in Unity 2021 and also don't recommend to use Vulkan on Android 7.x in older versions of Unity.
