My Technic Launcher Mod Packs Are Upside Down.... Help?H

[LuchiFoti]

Lately I've been encountering a problem where as soon as a try to play and Mod Pack the white Mojang loading screen is upside down, along with the rest of the game. It all functions how it should, its just upside down. If you know any fix for this please post it and if you are encountering the same problem please shout! Thanks for any support and help.
