1.17 update, refuses to render after going through Nether portal

I have the latest Optifine, 1.17-OptiFine_HD_U_G9_pre19, and sometimes it plays fine.  Though I haven't met any goats yet!  But sometimes it just doesn't render and I can walk right up to the cut off and not past.  This happened after going to the Nether. Also when going back to the overworld. The mobs are also glitching when this happens. and shooting arrows results in dancing arrows.  I have a RTX3070 i9 10850k so I don't think it's my processing power.  Reloading doesn't solve it.
