Created attachment 216138 [details]
the file include a simple figure that does not show correctly in evince. Also screenshots of the same figure in acroread (ok) and evince (wrong).

This is a bug I found 2 or 3 years ago but I though that was pstricks related. However, it seems is a bug of evince.

I created a latex figure using pstricks to shadow the area under x^2.
I used latex + dvips + ps2pdf14 to create the pdf file.
Evince does not show the figure properly.

evince myfile.pdf => WRONG

However,
printing the file, from evince: CORRECT
evince myfile.ps => CORRECT
acroread myfile.pdf => CORRECT

I attach the .pdf file that includes:
a) the problematic figure: this changes depending the viewer you use.
b) screenshots of the same figure with both acroread (left) and evince (right)

And this is the .tex file.
