Android Auto with my S21 is basically unusable. It is VERY laggy. I am running the latest OneUI beta 4

I have already tried factory reset the phone, change different cables, and use different versions of the AA app. it runs at 1 or 2 fps maximum. terrible. Here is a video comparing the s21 with the s20, on the same car and same cable:
