Recently tried downloading b4nny's config, booted up a custom 24/7 2fort server to test and it was flashing blue, me not playing that map very often decide to just go to dustbowl instead, and instead I get the same flashing issue as 2fort, hooray! It flashes like a baby blue colour and makes me want to die because I have no idea how to fix it, I'm using a GTX 1070 Ti if that helps..
Also I was running mastercomfig toaster earlier completely fine, no issues whatsoever
