PLplot does have some precision problems, e.g. the devices are limited to a 16
bit address space.  Usually this isn't a problem because physical plotting
devices are similarly limited in resolution -- it comes up only (AFAIK) when
zooming at high magnification.  There is some work underway to eventually
eliminate this problem but it will take some time.

However this doesn't sound like the problem you are having.  It might be a
bug.. if you could submit a test case that illustrates the problem (in
whatever language binding suits you), that would help.
