What I don't understand is how I have never seen random garbage, it is always this transparent yellow.

The attached png should be white text on a fully transparent background. At most resolutions, the transparent area around the text is partially transparent yellow.  It is never another color, the problem is very consistent. If I render into a 640x480 image using otherwise identical code, I get the correct output.  However, 640x85 has the yellow problem.  This leads me to believe that stride alone is not a factor. This was output by cairo win32 using the toy text functions into a 178x85 image surface.  Other tests have used circles or rectangles to rule out problems with the text functions. Regardless of what is used to save or display the image the problem still exists. Any suggestions would be greatly appreciated.
