The first a.eps is shown at the correct plave;
the second one is shifted to the left;
the thirs one is shifted to the left more;
the fourth one is shifted to the left still more
all .eps files are positioned correctly
convert bug.dvi to bug.ps, bug.pdf which are shown (by okular and by other viewers) correctly. Only bug.dvi is affected.
I am sure that earlier versions of okular displayed such .dvi files correctly. Unfortunately, I don't know starting from which version the problem appeared.

Upstream bug https://bugs.kde.org/show_bug.cgi?id=342735
This bug is still present in okular-5.9999.
Upstream suggests this is a ghostscript, not okular bug?
