Minecraft rendering problems?

Graphics Card: GTX 760 (4GB)
When using 16 chunk render distance on minecraft 1.7.9 (unmodded singleplayer) purple lines and jagged curves will appear in the distance. Do you know a setting in minecraft or the NVIDIA that will fix this.

Can't say i do any rendering but i love minecraft i always catch the pigs and i always kill the zombie pig men when i go to the nether its so awesome i once played for 4976 hours straight don't ask.

Make sure your drivers for the GPU are 100% current and and also install optifine, that may fix the problem.
