I Updated my Graphic Driver to 10.18.10.3621. After this sometimes Minecraft screen started to blink, usualy when the screen isn't in movement showing Items or just a white screen for like a quarter of second.
Items on the inventory sometimes blink.
Some buttons in GUIs appear half.
Same with the HUD of the item bar, health bar and food bar.
