I've had this problem for a couple weeks now. It starts off with some chunk loading problems (I'm pretty sure it's chunk loading), and they disappear and reappear fast, like a flickering screen. Sometimes it gets to be the whole screen doing this. Then, as in some of the images, the text has a weird black outline around it and signs become unreadable. Then everything flashes weirdly and turns black, or just simply disappears. It does not force a crash, but eventually I just quit minecraft.
Today, I reinstalled my whole minecraft folder from scratch, and the same thing happened.
Also, this happens in all of my minecraft versions.

I have not found any other user with this problem. Ask me any question, I just want this to be fixed.
