So when I look up at the sun, it will get a yellow center surrounded by a huge black box, when I shift the viewing angle slightly it goes back to normal (see screenshots).
I eliminated it as being from the texture pack as I removed all texture packs and it does it with the default textures too.
My list of installed mods are listed below in a screenshot.
Thanks for any assistance on this.
Okay, I removed the WAILA mod and it went away, the sun is now normal again. Don't know why that would have affected it.
