Hello! I've been trying to find a solution to this issue for a couple of hours now. Every thread I found seemed to come to the conclusion of reinstalling direct_x or something from Microsoft (I forgot what it was called already). Anyways, all I'm doing is trying to make a fragment shader that turns a sprite white. However, my game keeps crashing and giving me an error telling me that it's an "invalid shader." I've tried the solutions I mentioned before and I'm at a complete loss. What should I do?
