I’ve had this problem for about a month and a half, but not sure.
Whenever I go onto singleplayer, or maps that don’t overlay a texture over the screen, I have that purple and black missing texture stretched across my entire screen, blocking my view of everything, except for my health and the “Q” menu.
I’ve tried everything that I know, and also everything my friends know. Halp.
Here’s some pictures, if that helps.
