Well, dvi (standing for "[printer/viewer] device independent") is NOT
(originally) intended to handle any printer-driver-specific commands other than
including a mechanism to pass them through unmolested to the device dependent
driver. Postscript is such a printer-specific language. So problems for the dvi
viewer around postscript parts are to be expected.
I did not have a look at the files, but I agree that if the output of dvips is
correct, then that's a strong hint that the dvi file as such is fine. dvips per
design knows how to handle dvi in the special case of postscript output, and
knows how to handle the passed-through postscript commands.
In contrast, per (original) design, xdvi only is expected to know about dvi
display and about X special commands. In itself it has no reason to handle
postscript special commands, though I know it goes to some lengths trying to
handle those aswell. So I would expect problems around any postscript
constructions within the dvi when viewed with xdvi.
In fact, before switching to pdflatex for most of my work, my workflow was,
precisely for this reason, to always call dvips immediately after latex, and
then view the result with gv or any other postscript viewer.
