The second page is right vertically centered. And the third page shows that the white space isn’t added before the first paragraph in a normal page (no makeup).

This is the first issue, isn’t it a bug? Or what am I missing?

TeX inserts the \parskip value which is set by \setupwhitespace before your text in the makeup environment. Note that this happens only when you have skip before the text (e.g. with the default top=\vss setting) at the begin of the environment.

The following low level example demonstrates this:

\setuppapersize[A6]

\starttext

\dontleavehmode \ruledvbox to 3cm{\hsize=4cm text} \ruledvbox to 3cm{\hsize=4cm\parskip=2ex\relax text}

\dontleavehmode \ruledvbox to 3cm{\hsize=4cm\vss text\vss} \ruledvbox to 3cm{\hsize=4cm\parskip=2ex\relax\vss text\vss}

\stoptext

Many thanks for your reply, Wolfgang.

So the a workaround would be to use \blank instead of \par or a blank line, wouldn’t it be?

You can flush the content of the buffer in a \vbox where you set the whitespace at the begin of the box. \def\startSlide {\grabbufferdata[SlideContent][startSlide][stopSlide]} \def\stopSlide {\startmakeup[standard][align=middle] \vbox\bgroup \setupwhitespace[big] \begstrut\getbufferdata[SlideContent]\endstrut \egroup \stopmakeup} \setuppapersize[S8] %\setupbodyfont[100pt] \showgrid \starttext \startSlide program content \stopSlide \startSlide descender \stopSlide \stoptext Wolfgang
