hi everybody,I am also encountering the misalignment issues discussed in the above mentioned bug reports with assorted third party fonts (using groff 1.22.4).
as far as I have understood the discussions in those threads, the problem seems to have been attributed to a naming collision (or rather the presence of a sqrtex glyph in the font)? in this case, I just want to report that for me the problem definitely is present*without* the new fonts defining/containing a sqrtex glyph themselves (and I verified that the sqrtex -> radicalex fallback substitution/redefinition takes place for them).
attached a pdf (via grops) with examples of what I see.question: what is the current best short explanation what is going wrong here (and why it does effect different fonts in such a pronouncedly different extent) and whether/how the user
can patch it away somehow (or even better if there might be a real fix any time soon :))? personally (since using eqn a lot), this issue is quite serious since it effectively prevents serious use of non-standard fonts... best, joergps: probably known, too, but for completeness: the MacOS pdf rendering engine can/does cause additional problems, so better view otherwise ;).
