Builder would have to reset the walls as static. Then it would turn invisible even for your.....likely integrated graphic card. Basicly when builder can't see them right in the toolset, noone would see them in game, no matter what graphic card they have. I had the same issue with my old computer, and found this solution, at least for areas I've build myself. But it's hard to convince anyone to reset all the invis walls there are, when they don't have the same issue as you do.
Just wanted to update on this issue - Following the above advice, I'd gone through and deactivated all invisible walls.
The changes should be visible by next reset, if not before.
I don't have any way of checking if this was successful myself, so I'd appreciate it if anyone still seeing red walls around my areas after the next reset would let me know.
