My computer is 32G RAM, 8 cores
Statistically, the number of players playing the giant map is very small, so this bug seems to be rarely mentioned.
But as long as the number of civilizations on a giant map increases, it is easy for the borders of some civilizations to begin to disappear during the game.
I thought it was a problem with computer accessories, but new computers still have this bug.
However, if national borders (boundaries of influence) are not shown, it will interfere with cultural victory.
I hope the development team can handle it as soon as possible
