Removal of either tikz, grid or makeup is sufficient to make the blank
disappear.
I am failing to see how these three interact.

My versions:

Here is the related SE question:
http://tex.stackexchange.com/questions/284972/tikz-causes-blank-page-in-front-of-context-makeup-with-grid-layout

Can anyone explain the interaction or provide a workaround?


it's a bug in tikz ... it uses an extra file that needs to be opened 
immediate in order not to introduce an interfering node


for now, in cont-new.mkiv put this:

\unexpanded\def\openout{\immediate\normalopenout}

Re: [NTG-context] Bug with TikZ module ?

[Fabrice]

Hi,
This is true, but as I gradually abandoned LaTeX for ConTeXt, I'm a 
little too quickly precipitate. In addition, I prefer TikZ to PSTricks 
that I do not control very well, pending the integration of PSTricks in 
Context.

The solution \strut you propose works perfectly.
Regards,
Fabrice

You have the same result with LaTeX, so the bug is not with ConTeXt. TikZ 
is aligning at the bottom of the box rather than at the baseline.


IIRC, there is an option to align at baseline in TikZ. Otherwise, you 
can try adding `\strut` in each of the labels, so:


\node at (...) {\strut ...} ;

etc.

[NTG-context] Bug with TikZ

[Xan]

Hi,

I don't know why and how when the page begins with a tikz picture, a piece of 
text is blue?

See that:

\item Quina velocitat duu a cada tram?
\item Emparella aquest gràfic amb la història que correspongui:

\item \startframedtext En Tomeu camina lentament. Després d'una estona, se

\item Elegiu una de les opcions següents:

Is it a formal bug?

My version is the latest stable: ConTeXt  ver: 2014.01.03 00:40 MKIV current

I attached the file (pdf)
