Hi Gonzalo,

From a quick visual inspection, nothing obvious comes to mind.

I wonder if the parameters to the matrix need to be normalized or something?

Anyway, do you have (or can you make) a little standalone sample that uses that code, and I'll give it a spin once I'm near a real computer again!
Find attached a program that shows the issue.  The first time draw_pixel() is called, the matrix error does not appear.  On the second and other calls it does.
