    Matrix/Vector/Quaternion Issue

    I've been writing my own Matrix, Vector and Quaternion classes for use in my engine that I'm currently updating to support OpenGL 3.2+.

    I've looked over every possible detail, or so I think I have, and cannot fix this error I'm getting. It cuts out the top right portion of the image with the line being rather jagged. It originates from exactly the top left corner, drifts diagonally down to the center of the screen and then changes to a shallower angle towards the right of the screen.

    Better explained by the picture below:
