[Tex/LaTex] Beamer template shading background

backgroundsbeamer

I have a problem with the background of my beamer slides. When I compile it on my PC (Windows 7, TeXLive 2015) I get the following background:

But when I compile it on my MacBook (Mojave, TeXLive 2018) I get the following background:

How can I fix it to get the first one?

You first set your yellow-red background, but later you overwrite it with \setbeamertemplate{background canvas}[vertical shading][bottom=red!10,top=blue!10]

If you remove this line, you get the yellow-red shading.

Some other comments about your code:

The incorrect shading of the shadow in your first image indicates that your beamer version is seriously outdated. You should update your tex distribution
the beamer option red is obsolete. Use \usecolortheme[rgb={0.7,0.2,0.2}]{structure} instead
You don't need xcolor, graphicx or url with beamer
don't load packages multiple times
It makes little sense to load multicol with beamer, because beamer has it's own column mechanism
you should not use epsfig in any document written in this millennium
times is obsolete, there are much better packages for times font
instead of colortbl better pass xcolor={table} as documentclass option to beamer
The new line after the optional argument of \date makes no sense and the mandatory argument is missing

% !TeX TS-program = xelatex

Hi some thing like this could help:

\documentclass{beamer} 

\title{Stackxchng} 
\author{McCool} 
\institute{sth}
\date{the day the music died}   



\begin{document} 

\setbeamercolor{my thing}{fg=red, bg=black}% you can use every beamer color 
 \setbeamertemplate{title page}
   { 
\begin{beamercolorbox}[ht=2cm,wd=\paperwidth, left, sep=.5cm]{my thing}
 \color{black}Upper % use every color you want
\end{beamercolorbox}%
\vskip0pt plus 1filll % see beamerusersguide

\begin{centering} % some Text Macros
 \inserttitle 

  \insertsubtitle 

 \insertauthor 

 \insertdate 

  \insertinstitute 

   \inserttitlegraphic
\end{centering}
\vskip0pt plus 1filll % again tantau magical
\leavevmode \begin{beamercolorbox}[ wd=\paperwidth, ht=2cm, sep=.5cm]{my thing}
  \color{black} Lower % or what ever you like
\end{beamercolorbox}%
}



\frame[plain]{\titlepage} % PLAIN!

Hope that helps

[Tex/LaTex] Background image in beamer slides

You can also use \setbeamertemplate{background} {\includegraphics[width=\paperwidth,height=\paperheight,keepaspectratio]{background.jpg}} (where background.jpg is your picture).

A sample background:

enter image description here

Code

\documentclass{beamer}
\setbeamertemplate{background}
{\includegraphics[width=\paperwidth,height=\paperheight,keepaspectratio]{background.jpg}}


\begin{document}

\begin{frame}

\begin{exampleblock}{Test}
\begin{itemize}
\item First item.
\end{itemize}
\end{exampleblock}

\end{frame}

\end{document}

Edit

To answer the comment by the OP

Suppose I want to use african village (google image) as a back ground in some of my slides. But then written documents will be unclear. How one can convert the image as a water marking?

Here one can use the opacity option provided by tikz as

\setbeamertemplate{background canvas}{\begin{tikzpicture}\node[opacity=.1]{\includegraphics [width=\paperwidth]{example-image.pdf}};\end{tikzpicture}}

One can change the opacity values from 0 to 1 as per demand.

The code:

\documentclass{beamer}
\usepackage{tikz}
\setbeamertemplate{background canvas}{\begin{tikzpicture}\node[opacity=.1]{\includegraphics
[width=\paperwidth]{example-image.pdf}};\end{tikzpicture}} % only for the image: http://ctan.org/pkg/mwe
%      \setbeamertemplate{background}{\includegraphics[width=\paperwidth]{example-image.pdf}}
\begin{document}
\begin{frame}{Testing Background Image}
    Hello!
\end{frame}
\end{document}
