first of all: Happy new year everybody!

I am porting an application of mine from osg 3.4 to 3.6 .

I have a strange problem with text objects in anaglyph stereo. Some of
them are not correctly separated to red / cyan, they stay in their
original color (and thus produce heavy artifacts when viewed through

The problem did not occur with version 3.4. I can provide an .ive-file
that shows the error (with osgviewer when viewed in stereo), but this is
33 MB in size, so I thought it would not be welcome to send it to a
mailing list.

Strangely the problem does not show on all of my text objects, so maybe
someone has a pointer for me what I can to on my side to prevent this.

You can find the testfile here:

It contains a co-ordinate system, the numbers on the axes show the
symptoms whereas the two point-labels (which I have included for
reference) do not.

Best regards,
