  The problem is that the shadow of the frametitle fades to white. A quick solution would be to disable the shadow setbeamertemplate{frametitle}[default][colsep=-4bp,rounded=false,shadow=false]

Warsaw uses the shadow outer theme which applies a shading after the frame title:

  pgfdeclareverticalshading{beamer@topshade}{paperwidth}{%

    color(0pt)=(bg);

    color(4pt)=(black!50)}

One way to hide the shading is to redefine it so it matches your canvas background color:

  pgfdeclareverticalshading{beamer@topshade}{paperwidth}{%

    color(0pt)=(black);

    color(4pt)=(black)}

this redefinition has to be done AtBeginDocument. A complete example:

documentclass[ ]{beamer}

usetheme{Warsaw}



makeatletter

AtBeginDocument{

  pgfdeclareverticalshading{beamer@topshade}{paperwidth}{%

    color(0pt)=(black);

    color(4pt)=(black)}

}

makeatother



title{Footer right}

author{Footer left}



begin{document}



{setbeamercolor{background canvas}{bg=black}



section{First Section}



begin{frame}

  frametitle{Frame Title}

  color{white}{White bar beneath title removed}

end{frame}}



end{document}

The result:

Notice that we are only hiding the shading: to remove it completely, one would have to make a local copy of beamerouterthemeshadow.sty, rename it and make some otther changes, since the shading is added with addtobeamertemplate. Hiding the shading, however, is enough in my opinion.
