There was some speculation that the green hue bug was only occuring on later M chips, but i can confirm that I was experiencing the bug last week on my M1 Max (macOS15.6.1).
Because of this and the other bugs, I tweaked the setting according to the OP here (as it was at the time) and I haven’t experienced the bug again.
I should also say the the performance improvements have been notable throughout the beta!
I might try to turn up some of the shadow setting now and see what happens.
