The attached updated hack works for me with 1.9.22 for Medieval Total War, do you have plans to send it to either upstream or stagging by any chance?
I don't have any plans to submit this. It's only a hack. It does not fix the actual issue.
A proper fix would be to implement copying of depth/stencil buffers in system memory.
