To provide more information, we currently:

  1. Copy/readback the texture from the RDD to the content process
  2. Copy that from the content to the compositor process

And if it is a D2D or accelerated canvas, we may reupload the texture back to the GPU.

All of this when the texture is already accessible in the compositor process when we replay the recording without any copying or readbacks. There is a lot of low hanging fruit to improve performance.
