Issue was caused due to a mistake in the sprite batch renderer where the MathHelper.PiOver2 was incorrectly made negative during one flip combination compared to another. The issue also surfaced in the graphics device renderer since it was applying the horizontal and/or vertical flips to the UVs first and then the diagonal flip, but the diagonal needs to be applied first since it swaps the uvs.
