Optifine does not fix this problem. I can sometimes see various tools and golden apples flashing on the screen. The chunks sometimes do not load. The menu also flashes. Java is updated to the latest version. Specs below.

-MSI Z97-G55 SLI Motherboard
-8GB(2x4) DDR3-1600 RAM(Avexir)
-Intel HD 4600(reinstalled, latest drivers, performance mode, not fixed)
