>>It is not clear to me what the exact relation is, however.  It may be that
the problem just surfaces with different sizes.  The change results in
pango_font_description_set_size receiving numbers that are rounded rather
than truncated, so ?>>pango_font_description_set_size will receive a number
that may be larger by up to 0.5 than the exact number.  I would think that
this does not affect the overall problem but will likely change the cases
where those are most prevalent.

The problem bars are set to \abs-fontsize #12.   In trying to find a fix for
2.18.2, would it be worth testing other values close to 12 that minimize
rounding error?  What is the base value?
