Well the problem in my case seems to be this line in xrender.c:

1891: if (!devSrc->bitmap || GetObjectW( devSrc->bitmap->hbitmap, sizeof(dib),
&dib ) != sizeof(dib))

GetObjectW is returning less than sizeof(dib). I could workaround this changing
the line to:

1891: if (!devSrc->bitmap || !GetObjectW( devSrc->bitmap->hbitmap, sizeof(dib),
&dib ))

But after that I'm getting a page fault in:

1955: argb = (argb & 0xffffff) | source_alpha;

So I have to study a little more the code.
