Hello there,
Summary: Support for 24-bit true colour, added in Emacs 28.1, breaks
colours in Emacsen built without X support and running under
GNU Screen (v4.08.00).
Steps to reproduce:
1. Build Emacs >= 28.1 without X support. The two configurations I have
tested are below:
./configure\ ./configure\
--prefix=[…]\ --prefix=[…]\
--enable-check-lisp-object-type\ --enable-check-lisp-object-type\
--disable-acl\ --disable-acl\
--without-dbus\ --without-all\
--without-gconf\ --without-x\
--without-gif\ --with-file-notification=yes\
--without-gsettings\ --with-gnutls\
--without-jpeg\ --with-gpm\
--without-modules\ --with-json\
--without-png\ --with-mailutils\
--without-rsvg\ --with-modules\
--without-selinux\ --with-native-compilation\
--without-sound\ --with-libsystemd\
--without-tiff\ --with-small-ja-dic\
--without-x\ --with-sqlite3\
--without-xpm\ --with-threads\
--with-xml2\
--with-zlib\
2. Launch a terminal program (e.g. GNOME Terminal) and run GNU Screen
(bypassing any .screenrc):
$ touch foo
$ screen -c foo
3. Run Emacs with 24-bit true colour active and observe the broken colours:
$ COLORTERM=truecolor ./src/emacs -Q

4. Run Emacs with 24-bit true colour inactive and observe the correct colours:
$ COLORTERM= ./src/emacs -Q
