the problem seems to be related to screens,

background=color,backgroundcolor=red

works ok, (screens are normally only used in (page) backgrounds and there 
they don't nest, and since they don't form a color stack (just raw gray 
scale switches) this goes wrong inside color, maybe i should implement a 
stack)

================ can go into cont-new.tex ================

\def\setrastercolor#1%
   {\edef\@@cl@@s{#1}%
    \ifx\@@cl@@s\empty
      \let\@@rsraster
    \fi
    \setevalue{\??cr\??rs}{\colorSpattern}}

\def\localstartraster[#1]%
   {\bgroup\setrastercolor{#1}\localstartcolor[\??rs]}

\def\localstopraster
   {\localstopcolor\egroup}

\def\startraster[#1]%
   {\bgroup\setrastercolor{#1}\startcolor[\??rs]}

\def\stopraster
   {\stopcolor\egroup}

This alternative is slower, but run on top of the color mechanism
