Per-object shadow corrupts on Android Vulkan

• Use UE 4.25.1

• Create a new third person game.

• Use these settings: Blueprint, Desktop / Console, Maximum Quality, No Starter Content, Raytracing Disabled.

• Click on the CubeMesh actor, and enable Dynamic Inset Shadow.

• Enable Support Vulkan in Project Settings.

• Launch to Android device. I'm using a Galaxy S9.

Most of the viewport will be corrupt in a very obvious way. RenderDoc frame capture seems to indicate that per-object shadow draws are causing the corruption.

Scene looks fine with Support Vulkan disabled.
