I upgraded my DejaVu fonts (http://dejavu-fonts.org/) from version 2.32 to 2.33, and I didn't bother to restart any of my programs because such an action didn't even ocurr to me as being necessary. However, I think that this upgrade caused an inconsistent state for at least Firefox 4.0.1, which I assume uses fontconfig to manage fonts. The result was that at least a few of the variable-width serif ligatures were being rendered with the wrong glyphs (presumably because glyph locations had changed due to the upgrade); see here for a screencast of the problem: http://www.youtube.com/watch?v=zZoK4BhZaCs After running a new instance of Firefox, the problem seemed to be resolved, corroborating this hypothesis. Is this a fontconfig weakness that could be resolved?
