I was using one of the default Unity skyboxes for testing my game, and I went into play mode. Everything worked fine, until I stopped playing. Then this happened:
As you can see, you can see the corners of the skybox, and the images became pixelated. I even changed the skybox (several times) but each one turned out the same. This started happening to several other projects I had, and I’m really confused why. I would submit a bug, but I have no idea how to replicate the problem. How do I fix this?
