use F3+T it fixes the visual errors temporarily but not forever
also someone else has reported this too: MC-295908
I also made a report on this under MC-295862 and F3+T seems to temporarily fix the visual errors, but not for long
edit: it still happens, just much less often and much less egregiously and not right on startup
I just tried allocating an extra 1 GB to my minecraft in the launcher, and now it works fine. IDK what’s up with this though. Originally 2 GB (now 3) allocated out of 16 GB on a somewhat old windows pc.
I don't think I was clear in my replies: rendering of the world and freezing was no longer an issue after increasing ram, but text colors progressively messing up as seen in the other report still happens and can be temporarily fixed with F3 + T, but it comes back faster each time I press F3 + T
