That commit simply made Cairo being available by default, if found on the system. It didn't change any code. Are you saying that non-Cairo build shows this problem as well, after that commit? Or is the problem limited to Cairo builds on your system? > 1. create a ~/.emacs file with: > > (define-fringe-bitmap 'empty-line [ #xff ] nil nil '(top t)) > (setq-default indicate-empty-lines t) > > 2. emacs ~/.emacs => the empty lines fringe bitmaps are displayed > correctly, with a solid black column. > > 3. emacs --daemon > > 4. emacsclient -c ~/.emacs => the empty line fringe bitmaps are the > default ones, which are 4x1 pixel horizontal black lines. In general, display features that need GUI framework should be turned on from after-make-frame-functions or server-after-make-frame-hook to work reliably in daemon-based sessions. However, if this used to work, it would be good to understand which change broke it. But I doubt that the commit you identified is the culprit: I see the same behavior on MS-Windows, where Cairo and the commit you pointed to have no effect whatsoever.
