Dear Hans,
The following example worked perfectly fine with the version of
ConTeXt MKIV I was using one hour ago (no idea which version, but
something less than two weeks old). It still works OK with MKII and it
works much worse in the real document that I'm using.
In my document both images are completely screwed up. Here it's only
the second one and if I comment out the first one, the second figure
comes out fine, so I'm a bit clueless about what magic is going on
inbetween.
Nothing in TikZ has changed (I'm still using the "frozen" version from
November 2009 from minimals), so it must have something to do with
ConTeXt MKIV. It just messes up with some boxes on the page in some
unpredictable way.
Hans,
thanks a lot for the really nice simple example.
I have no clue ... maybe some magic tikz variable (or shared register) that
does not get reset?
I have no clue either, but this has never been a problem before and it
still works perfectly in both pdfTeX and XeTeX. So something really
looks suspicious on the MKIV part.
After some tracing and hard thinking Taco and I found interesting spaces
showing up in the output that result from a kludge in tikz:
Normally one will use \ignorespaces to catch spurious spaces but tikz
invokes \nullfont assuming that its fontdimen 2 is zero. But, in context
it no longer is (prelude to delayed font loading).
You can put this in cont-new.mkiv as a temporary hack
\let\normalnullfont\nullfont
\def\nullfont
{\fontdimen1\normalnullfont\zeropoint
\fontdimen2\normalnullfont\zeropoint
\fontdimen3\normalnullfont\zeropoint
\fontdimen4\normalnullfont\zeropoint
\fontdimen5\normalnullfont\zeropoint
\fontdimen6\normalnullfont\zeropoint
\fontdimen7\normalnullfont\zeropoint
\normalnullfont}
