With some of my recent patches, particularly: [PATCH] GTK3: Simplify board_end_drag() https://lists.gnu.org/archive/html/bug-gnubg/2026-05/msg00015.html
GTK3 is in a more usable state for gnubg. Some distros are already disabling the default GTK2 build, and we may be able to resolve this Debian bug with a new gnubg release: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1110213
