--- Comment #5 from Henri Verbeet hverbeet@gmail.com --- Tessellation shader shader support is still a little less solid than the other shader types, so in that regard it's certainly plausible that there could be bugs in that area.
In case it's useful to you, note that vkd3d_compute_dxbc_checksum() can be used to compute DXBC checksums. That's currently an internal function, but we will likely expose DXBC manipulation interfaces in a future release.
In any case, thank you for the bug report.
