Hi Eli, My emacs is the compiled in the editor's repo for 15.2 ( https://build.opensuse.org/package/show/editors/emacs), so I haven't any control on how it was compiled. With respect to the bug, I could reproduce it when I tried to replace a link in org-roam. Here it is the full backtrace. Thread 1 "emacs-gtk" received signal SIGSEGV, Segmentation fault. gui_produce_glyphs (it=0x7ffd8df127a0) at xdisp.c:29925 29925 struct font *font = face->font; (gdb) source /etc/gdbinit (gdb) bt #0
