            Description

            The pdf in question has an image that isn't properly clipped and obscures the underlying text. Normally this kind of issue falls under masking but in this case it's actually a transparency group issue.

            The Indexed colour space oft he image has transparency group definition which must be responsible for the transparency shown by acrobat.
