[Mac] 8 different graphics bugs, each isolated to one setting — with repro steps for each

And at Shadow Quality Fair, static world geometry stops casting shadows while characters keep casting. A character standing on a bridge casts a shadow on the ground underneath it. Above Fair, the bridge correctly blocks the light. At Fair, the bridge stops shadowing the ground — but the character’s shadow still projects onto it. Reproduced at native resolution, so this was never fault 18.

I’m holding off on a number for this. It doesn’t cleanly match fault 8 (offset and oversized) or fault 9 (boundary at fixed camera distance) — “shapes that don’t match their caster, varying with the sun’s angle” is a different description from either.

Now that I can actually see shadows where they’re supposed to be, I have finally witnessed fault 9 to an extent. At a fixed distance from my character, terrain shadows disappear, but not characters’ shadows. This was visible at 9-9:30 AM in Kharanos through the following steps:

1. I walked out of the inn and up to the signpost right by its entrance, turning to face the two mountaineers just north of me (one by the road in front of the entrance to the forge, and one atop the ridge next to him)
2. I walked forward towards the dwarf atop the ridge until the shadows visibly popped below him.
3. I backpedaled to find the hard line edge of the shadow.

I then observed that only the terrain’s self-shadowing was impacted, and when circling around that shadow, there were points when various triangles from the terrain stopped casting their shadow, producing a flicker that may have been what others described in other reports.

It is also worth noting that doodads in the world like the signpost maintain their shadow regardless of distance. The only time they disappear is when the shadows are set to fair, which I imagine is intended behavior and not actually a fault.

Furthermore, when I set my shadow quality to fair, the terrain’s self-shadow lingered until I moved away from it, then never returned.
