The best way to explain this is that anything metal, or having a shiny texture flashes red.
These are just a couple examples where the map was flashing Red. It hasn’t stopped since the previous day when it started meaning it’s been happening for a full 24 hours and I believe it began after selecting a workshop skin. It’s starting to cause strain on my eyes and might cause seizures in people who experience them. It’s a constant flashing unless I’m completely still.
