My Minecraft has been flickering white lines/spots randomly on the screen. It only happens in Minecraft and it does the same thing in single-player and multi-player. I have tried uninstalling and re-installing Minecraft and my graphics card. I also got my graphics card checked by its company's website to verify that I have the newest version of it; and since its only a Minecraft problem, as far as I know, then I don't think it's a graphics card problem. This only occurred after I updated my Windows 8.1. So I uninstalled the windows updates and it still flickers. My only guess is that the windows update changed and old config option and I can't figure out what it is. Any Ideas

Graphics Card: Intel(R) HD Graphics Family
Processor: Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz 2.30GHz
Installed memory (RAM): 12.0GB (11.9GB usable)
System type: 64-bit operating System, x64-based processor

I have tried changing everything I could think of too. Including taking my mods out and running Minecraft before I download forge again after reinstalling Minecraft.
