https://issuetracker.unity3d.com/issues/android-vulkan-msaa-gets-resolved-into-a-wrong-swap-chain-buffer-when-using-cameratarget-as-resolvetarget

There are artifacts after orientation change.

  • Workaround: Acquire swapchain image last as possible (effectively introduces another intermediate texture)

Test:

  • Orientation change
  • Correct resolve considering Vulkan pre-transform
