Hey everyone, okay so here's the thing, I just bought a new PC and when I downloaded Minecraft on it, as soon as the main menu opened I saw flickers of grey on it, and when I opened a world, every few seconds there'd be flickers of grey and purple lines and shapes. My drivers are updated and I have an integrated Intel HD 4400 graphics card, I'm not sure what I should do? Any help would be REALLY appreciated, thanks!
My Java is up to date. I downloaded the new launcher and it stopped the flickering in the menu only, it still flickers a lot in game unfortunately. But thanks anyway for your input!
Flickering screen, please help!
