Well, your're not alone.  My A2320 is EXACTLY the same as you described
above, and I know of two other A2320 owners who describe the same
performance.

If I may quote from page 1 of the A2320 manual:  "The A2320 Display
Enhancer board ... provides an alternate video display output that
yields an image with no flicker or visible scan lines in interlaced
or non-interlaced Amiga graphics modes."  Well, my A2320 does not do
this.  If nothing else, that 1/3 line at the top contradicts this
statement, but I, like Tyler, find the top right and bottom right 1/8
much more annoying.

Scott: I believe a correction of these video artifacts should be
a warranted fix/upgrade.  The A2320 unit requires the upgrade to
become what we agreed to buy and what we paid for.
