So trying this again the glitch does also appear to affect lighting as well as the skybox and therefor shadows cast on the ground in real time
This seems to be some kind of weird game bug as apparently it can also happen on PS5 https://www.reddit.com/r/FFXVI/comments/1bmss0x/game_breaking_glitch/
Edit: might be a different bug
A mix of game bug and DXC bug. Fixed in latest dxil-spirv.
