Same problem. The game seems to slowly build them up over time until the map is unplayable. Sometimes doesn't happen at all. No changes to the graphics settings help.
I'm experiencing the same bug, in some maps where certain areas have graphical issues that sometimes make the game unplayable. It’s not random there are specific areas where this bug always appears.
I'm playing on PC Steam version.
Specs:
CPU: Ryzen 5 5600X
GPU: Nvidia 4070 Super
RAM: 64 GB
Motherboard: ROG Strix B550-F
After testing different graphics settings, I noticed that the issue changes with the "Geometry Quality" option when I adjust this setting, the black lines and boxes move to different positions, but they don’t disappear.
