world rendering flickers when reloading the world

when relogging to a singleplayer world after being in the same session(not closing the game) the world starts to flicker
some chunks look like others and when i get close to them the either change to a random chunk around them or stay the same,
i also managed to duplicate the bug a few times and it seems to happen every time, the bug is ocurring even on other environments such as my brother's PC and the PCs that are in my school.
this bug will happen in the versions 1.8 and up(snapshots as well)

i know how to hot fix the bug, if i save the world and just relaunch minecraft it seems to fix the problem, but its just session based so it will happen only when being in 1 session..
