Bonjour,

I am facing a problem with tikz: with the following MWE, if you change
the page dimensions, uncommenting

% \hoffset -1in
% \voffset -1in
% \setlength{\topmargin}{45mm}
% \setlength{\textwidth}{110mm}
% \setlength{\textheight}{175mm}
% \setlength{\oddsidemargin}{50mm}
% \setlength{\evensidemargin}{50mm}

The rightside image (nombres tétraédiques) disappear while you get it
if you do not modify the page dimensions...

This problem does not occur with lualatex...

<---- MWE ----

\documentclass[a4paper,11pt,twoside]{report}

%% dimensions du livre

% \hoffset -1in
% \voffset -1in
% \setlength{\topmargin}{45mm}
% \setlength{\textwidth}{110mm}
% \setlength{\textheight}{175mm}
% \setlength{\oddsidemargin}{50mm}
% \setlength{\evensidemargin}{50mm}

<--- end MWE ------------

Is it a bug in xelatex (I tried both tl-2013 and tl-2014)?


Thank you for attention.
