Greetings again, okay, so... For some reason when fullscreen is set the camera stoped rendering to the rendertexture, so the rendertexture just continues to be the same thing So we added a check to see if the render texture has been disconnected and if so It'll reconnect which should hopefully fix any issues. TELL US IF THAT WORKED! We also fixed a few sound bugs that were cropping up. The programmer is confident this time. So, feel free to make him cry.
