That's known by many minecrafters as lag. Try turning your render distance down and graphics to fast instead of fancy.

This report says it's still happening in 1.8-pre1, but it should have been fixed in this version.

Its definatelly not lag cuz i was playing in a flat world and I have a super PC. anyway it has already been fixed so...
