Bug Description

During gameplay, there's some weird flickering in the shadows on the ground. Things seem to settle if I stay in one place for a while, but otherwise it's pretty constant. It starts immediately after starting free roam:

Expected Behavior

From gameplay videos on YouTube it looks like xemu didn't used to have this issue, so I figure this is either this is a regression or a macOS-specific quirk: https://www.youtube.com/watch?v=UR2Pb9HnqbE

I think this is related, but I may also add that:

1. Some elements like walls disappear sometimes especially if there are shadows expected to be in that direction

2. The car lights's origin point is depositioned and might cast an unexpected dark ball behind the car

3. Sometimes, in shadows, there is a graphics mask that makes the floor transparent.

upscaling for this game is not working right.
it will slow the game very down and causes graphic stripes in game

Upscaling still has slowdown and graphical issues.
Looks fine at Native Resolution (tested around 6 missions).
