The cause seems to be the use of QMatrix4x4 in the OpenGL2 painter.  It
seems like the QMatrix4x4 transformations are doing the matrix
multiplications from the opposite side compared to our previous class.
The arguments to scale were also incorrect since it used radians and a
(0, 0, 0) rotation vector.  I have attached a patch that should fix
these things.

The default behavior for screens is to fade in and out, but the theme is
free to change this,
