Default Textures Glitching out Completley

My Minecraft Default Texture/Resources (The ones that you start out with)
Are starting to act up really bad. If I break any blocks or mushrooms then the entire world turns Black or it does this Lines texture glitch. It doesn't seem to affect Tall grass or flowers but i noticed it when breaking Wood Logs and other Blocks. Sometimes it Even Just Does that when walking. It also only Recently did that when 1.7.9 Came out.
