I was able to reproduce this behaviour with the art backend (xlib and
cairo don't have it). I would expect that this is caused by slight
drawing differences in this backend. There already is a bug report on
that: #26050. It looks like art is drawing to a slightly smaller area
than it claims to do. Most likely a rounding error somewhere deep inside
the code.

The best solution for now is to switch over to the cairo backend.
