For the love of god and all of our 50 series users, someone find a fix for this bug. Any tech gurus?

I’m sure most people with the 50 series card are having this issue with all the maps that they play. It truly sucks because this is one of my favorite games and now it’s literally unplayable. there has gotta be a way to fix this
This map when you first start is bright and colorful, but after five rounds, it becomes completely unplayable Please don’t delete this!! It needs to be seen and fixed!!
