@TilmannR: do you also experience z-fighting when viewing the inside sides of the faces in the file previewer? Arlo James Barnes 10:32, 21 May 2023 (UTC)[reply]

Hi, @Arlo Barnes. I haven't actually looked at the code, but based on the visuals I'm guessing that during the shadow pass they apply a depth bias based on the direction of the triangle's normal, which improves the situation in the front, but makes it even worse on the back. The technical term is "shadow acne". TilmannR (talk) 18:28, 21 May 2023 (UTC)[reply]
