Hi Stanislav,

 Yes, I see your PS file is gray. The PS file I get is not exactly the 
same as yours. I have done a diff between my PS file and yours and I get:

My:
<  gsave  0 0 t black [] 0 sd 3 lw 1 1 1 c 2268 1538 0 0 bf
                                   ^^^^^^^^^^^^^^^^^^^^^^^^ 
                                     background is white
Your:
>  gsave  0 0 t black [] 0 sd 3 lw 1 1 1 c 0.95 0.95 0.95 c 2268 1522 0 0 bf 
                                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                                            Background is is gray

 I use the same version as you. So for some reason I do not understand yet 
your version has an extra "gray directive": 0.95 0.95 0.95 c
