This occurs since the switch to pyopengl (yay!) but only if python3-numpy is not also installed. I was able to eliminate the conversion of the matrix to its 1D / list form entirely. I think I got pretty good coverage of everything _except_ qt vismach in my testing, both with and without python3-numpy installed. qt vismach should be the same as tk vismach, as I made edits with the same intended effect.
