Attempt to log into Minecraft under the latest release, greeted with a black loading screen. Game will not load past this.
Opened the Game Output and noticed this:
"[16:02:11] [Client thread/ERROR]: 1286: Invalid framebuffer operation
[16:02:13] [Client thread/ERROR]: ########## GL ERROR ##########
[16:02:13] [Client thread/ERROR]: @ Post render"
Graphics driver recently updated (GeForce 378.49), launcher was updated aswell before this issue.
Reinstalled Minecraft several times, to no avail. Renamed the resource packs and mod folders, only to achieve the same result.

That error is caused by your graphics card drivers, first of all, lets discard it being the bugged version of the drivers and follow the fix in MC-112780
If you still have the issue after that, you might want to post a dxdiag in any of the community resources https://help.mojang.com/customer/en/portal/articles/1175661-minecraft-support-resources
