When viewing a PDF, some areas are blacked out, such as cells on a table. However, when I print them, they look fine. I have made sure "Show large images" is checked, as suggested from other forums.
I actually downloaded Reader X to see how a PDF appeared different from Acrobat 9. Their compatibility should have nothing to do with the viewability of the opaqueness in a PDF. Again, I only downloaded to compare/contrast.
I will, however, take a look at the video driver accelaration.
I don't think this is solved yet, though.
