i know about the overdraw prevention on FAQ but it didnt help me on this (and also, this looks different than the circle that follows you, su this might be something else)
looks like the chunk is already loaded, but is not rendering anything of it yet, happens connecting to a server adn also on single player in case this could help, i share here the connection of "performance mods" in case any of these could have incompatibilities i didnt found (very possible)
