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.
