I'm using SDL + OpenGL for a small game. When I run the game on my PC, it runs fine, but when I tried the same in college, the output was blank white with a few bright white boxes instead of the characters. All the data files are in place. I suppose the error is related to OpenGL. I'm sure its not related to texture format being RGBA or BGRA, because I'm checking for it. I currently don't have an image or video showing the faulty output, but here is the link to the original gameplay video.
