I'm trying to make custom background for my slides in beamer presentation, gradient one to be exact. It is going pretty good, mainly because of other people questions here, but I have one problem that I just couldn't solve.

When I use code like this:

\pgfdeclareverticalshading{myshadingE}{100bp}{color(0bp)=(black);color(100bp)=(white)}
\usebackgroundtemplate{
\begin{tikzpicture}
\pgfpathrectangle{(0,0)}{\pgfpoint{\paperwidth}{\paperheight}}
\pgfshadepath{myshadingE}{45} 
\pgfusepath{stroke}
\end{tikzpicture}}

I do have my gradient and all, but there is black outline (edges of the rectangle) visible on left and top side of slide. Can anyone help me with that one? ^^"

    I'm not sure I understand, but does removing \pgfusepath{stroke} solve your problem? – Nico Boni Nov 21 '13 at 16:02
  • I will be honest, I'm not entirely sure what I'm doing. :D It's more of trial and error process - I do have \pgfusepath{stroke} but it doesn't help me. :( – Dino Nov 21 '13 at 16:07
  • I was suggesting to remove it. Anyway, in different pdf viewers I got different results: maybe is your pdf reader that adds the black border? – Nico Boni Nov 21 '13 at 16:57
  • On all viewers I have currently installed on this machine I do see that outline. Removing \pgfusepath{stroke} helped me, thank you very much. ^_^ If you'll post this as an answer then I can accept it as a solution. – Dino Nov 22 '13 at 8:48

It seems the black outline was caused by \pgfusepath{stroke}.

With \pgfusepath{stroke}:
