I got a new laptop 4 months ago and I installed Minecraft, i entered and suddenly it began flickering. I saw a solution to flickering by rolling back video card drivers, I did. Then I was again on Minecraft, launched it, and it said "bad video card drivers", so I updated it back and back to flickering again. My video card i have is Intel HD Graphics Family.
Steps to Reproduce:
1.Launch the Game
2.Go to Singleplayer or Multiplayer
3.Load a World or Server
4. And starts the flickering (flashing, blinking)
