Your code line 144 is
spam_vertices[1][3].x = (SPAM_W-SPAM_W/4) << TMU_FIXEDPOINT_SHIFT;
I think you meant:
spam_vertices[1][2].x = (SPAM_W-SPAM_W/4) << TMU_FIXEDPOINT_SHIFT;

(second index should be 2, not 3).

But even after this fix, there is still a problem with the upper-left square. 
I'll look at it, but you can also try to reproduce the problem and get more 
information by using the test bench (cores/tmu2/test).
