My fake windows and :) bossfight are broken

[Funnymemes4ever]

When i turn on fake windows the background goes black and no matter what i do to the background it just stays black. also when the black background glitch happens the window that you have to shoot :) with goes invisible so i cant kill him. does anyone know how to fix this because it only happens when i have fake windows on

Same issue since I got the game. Hope there's a fix.
