When I play Minecraft I have this weird glitch where blocks turn black or randomly colored. I searched up on Google this issue but a lot say make the Mipmap level to 0, which I have tried but didn't solve the problem. I'm using Windows 10 computer - Intel(R) G45/G43 Express Chipset. Please if anyone has a working solution please reply to this post ASAP. Thanks! http://imgur.com/5ltARLS
Since you have no mods or resource packs: The first thing I would do is update my video card (graphics adapter) drivers to the latest available. This might also involve updating motherboard/chipset drivers if your card is integrated. If that doesn't help, try reinstalling other components one at a time. You don't need java if you use vanilla launcher. If you're using cracked launcher, update your java. Then delete and re-fetch the minecraft files for the versions you use. There's also a possibility that your video card is failing. If it's an integrated card, your system RAM might be failing. Download some system test/burn-in software or take the machine to a competent service center for testing.
