While I'm in a bug-reporting mood, there's another problem that's been plaguing me for a while: sometimes, seemingly at random, the line height calculations in st seem to get messed up. I suspect it may relate to my kerning patch, the font-fallback code or both, but since I have not been able to consistently reproduce the problem, and I don't generally build st with debug symbols, I've not dug into the issue. I've attached a screenshot showing the errant rendering. 99% of the time, things are fine and there are no gaps between the lines like that. In my config.h file, I have "static float chscale = 1.000001;" which is kludge to work around a Xft rendering issue as described at [1]. Regardless of the value of chscale, the line-height rendering shouldn't change arbitrarily / randomly.
