I downloaded a free PDF book from Suvudu.
http://a1018.g.akamai.net/f/1018/190...eversuvudu.pdf
When I display it in the Adobe Viewer at Zoom level 1, it is very small, but OK
I change to Zoom level 2, and I get:
Note that the Top Graphic and large Capital are missing.

Advance a Page.

This continues for the larger Zoom levels.
Set to View as XPDF and you get for Magnify 2 (8 key)
Set to Magnify 3

In all cases the M and graphic appear in the proper place.
RobertB can you submit this as a bug report?
