Hi all,
I am experiencing a problem with xelatex, with a very simple presentation I
wrote using beamer. It was written on a linux machine, and all is working
well.
Now I am using a mac (last update) with a mactex 2013 base system.
All needed packages are installed.
I get an error relative to the use of pgf shadows. In particular, xelatex
complaints about
** WARNING ** Error locating image file "pgfshadebeamer@headfade"
** WARNING ** Specified (image) object doesn't exist:
pgfshadebeamer@headfade
** WARNING ** Interpreting special command usexobj (pdf:) failed.
I made a lot of testing, but I was not able to solve the issue.
I paste here a small piece of code that reproduce the error in my machine

having stripped the normal logs for other operations.
If I run xelatex -no-pdf, it does not display any complaints in the
production of the xdv file.
However the same warning/error is given by xdvipdfmx.
In practice, the pdf produced does not show the gradient on the background.
Please note that if I add several other pages, they have the correct
background. Only the first page is "corrupted".
Please, is someone able to help me/reproduce this error?
Or simply could you give me some advice on how to solve it?
Best regards to all
Sincerely
F. Tramarin
