[RADV] - Path of Exile (238960) - "Trial Ape" enemy cause black artifacts to flicker on screen.

Description:

In Path of Exile (238960), the Trial Ape enemy type will occasionally cause a black square to flicker on screen. This issue occurs on both the Vulkan and DirectX 11 (DXVK) renderer.

I've confirmed the issue occurs under both LLVM and ACO using both master (8d9b52f4) or stable (8ec04634). Issue is not present on AMDGPU-PRO (20.50) or Nvidia (460.67).
