Another user recently reported problems with loading text in a background thread, which fits your problem too. This was recently and with the SVN version of the OSG so it looks like the problem persists. I suspect the problem is either in src/osgText/Font.cpp or the freetype plugin, or freetype itself. If we can pinpoint where the problem it should be easy to fix - something like adding a mutex to serialize the freetype API access. I don't have an app that recreates this problem with rather limits my ability to reproduce and fix it. So I either need an example that reproduces the problem or for others to dig into the relevant code and fix it. > Also, on a possibly related note, what happened to > "viewer.sync()" in osg 2.0?

The sync is effectively done inside the Viewer::renderingTraversals() method which is dispatched by Viewer:frame(). The updateTraversal() is also could from within frame() as well so one needn't call this either unless you want to replace frame() call by it consitient parts.
