terrain graphic bug

when i first downloaded the new minecraft 1.9.2, there is what happened

1. in the launcher log, there was something like [15:28:30 WARN]: Had local file but it was the wrong size... had 32455 but expected 134855

2.when i´ve created a new world, all the stuff went ok, but when i´ve closed and reopened the world, there was something like this (attached file)

PS: i cant fly with the elytra

question: does the solution works with ATI Mobility Radeon HD 4500 Series
driver version 15.7.1 ?
