Opened launcher. Clicked 'Play'. Minecraft window appeared, but stayed on the black screen. I tried again and the same thing happened. Left it running for about 5 minutes, and nothing happened.
Long string of code in development console reading:
[Client thread/ERROR]: @ Post render
[Client thread/ERROR]: 1286: Invalid framebuffer operation
[Client thread/ERROR]: ########## GL ERROR ##########
repeated over and over.
Screenshots of the blank screen and dev console attached.
Tested with all recent snapshots and 1.7.4
Steps to Reproduce:
1. Open launcher
2. Click 'Play' while running Minecraft version 1.7.4 or any recent snapshots
