I am making a game engine, and to make the game world, I decided to use cuboid geometry. I have cube vertices in a VBO, and I also use an IBO for it as well. Whenever I place 2 cuboid objects right next to each other on the same plane, I can see these flickering pixels between the two. I found out that these pixels are actually little holes, and I can see the background color through them. How can I prevent this? Thanks!
Heres a picture:
