DXtory seems to struggle with SOMA's openGL version, or something, and while the game runs perfectly fine, any footage recorded seems to suffer from this odd corruption.
Update: noticed that the overlay tends to flicker into the recording whenever the frame jitter happens. Possibly two symptoms of the same bug?
