I use ensime for Scala editing, and I've come across a strange display bug
which is only present in `emacs -nw`, `emacsclient -nw` or just `emacs` from
the `emacs-nox` package. It has to do with some very jarring underlining
that occurs during ensime's "semantic highlighting". The issue does not
occur in normal GUI emacs.
I've contacted the ensime maintainers, and while they can reproduce the
bug, they claim it isn't an ensime problem. Hence I'm here.
The ensime bug report (with pictures and instructions to reproduce) can be found here:
https://github.com/ensime/ensime-emacs/issues/440 Thanks for any help you can give.
