Black & White screen after minecraft launcher

Hi! 
Whenever I start minecraft, my screen goes white and when I maximize the game the 'remaining pixels' go black. (Picture in attachments) Basically: my screen is just black and white and I cannot see the menu or anything. Weird thing is; I can still press buttons eventhough I do not know where they are. The only problem is that I just cannot see anything.

I've looked for solutions on the internet, saying I should update my graphicdrivers. I have a laptop with two graphics cards, and both are fully updated. The weird thing is that this only ocurred after I updated them. I tried rerolling the update too, but it wouldn't let me. And yes: I did reinstall minecraft aswell and of course restarted my computer several times. I tried disabling my iGPU too, but that didn't help either: instead I could not start the game at all.

Note: This is AFTER the ingame launcher. The launcher works just fine, it's really the game Minecraft itself.
