Graphical / Rendering issue, snapshots to 1.16

 

First see the attachments
 
Well, I guess this is rendering issue, and I have it for the second time (The first has occured around the 20w10a snapshot, I sent one screenshot). It occur suddenly, no matter what I do, Minecraft works without any changes (resource packs itp.), just pure minecraft snapshot. After any action that requires reloading (e.g. turning mipmapping off / on) everything returns to normal.
In logs bolded event coincidends with time of occurence of issue:
