The customer reports and I've verified that the attached file renders differently in gshead (r8997) and Acrobat Reader. Specifically the bottom block text is rendered in black by Ghostscript and gray by Acrobat. The command line I'm using for testing: bin/gs -sDEVICE=ppmraw -o test.ppm ./trans.pdf Note that this file had a more severe problem reported as bug 689309, which has been fixed as of gs8.62,

Just to clarify, this file has never rendered correctly by Ghostscript. Ghostscript 8.61 and older rendered the file with a gray rectangle obscuring the text and 8.62 and later fixed the rectangle problem but rendered the text in black instead of gray.

The source of this issue is identical to that of 689968. That bottom text is defined by a vector graphic. There is a graphic state that is set prior to drawing it, which has an Soft Mask defined. This soft mask image should be used when the solid fills occur. Currently, our code only uses softmasks as part of transparency groups. We really should be able so associate the softmask with the graphic state. The fix for this is going to be involved and I am just now starting the process. For further detail see 689968.
This is really a duplicate of the issue discussed on bug 688601 and bug 689968 Rendering the 'SMask' changes the FillColor so that when the subsequent text is painted, the FillColor is black instead of gray. *** This bug has been marked as a duplicate of 689968 ***
