Description rnddim 2016-08-27 12:06:07 UTC
While using the stated versions of emacs under the GTK+-3 toolkit, attempting to maximize the initial window results in the editor not updating properly. Emacs acts like the window is maximized, but doesn't display the screen properly (using the previous screen contents) aside from a top-left corner of the same size as the un-maximized window.

This problem does not exist when using the Motif or Athena toolkits.

Comment 1 Ulrich Müller gentoo-dev 2016-08-31 03:25:39 UTC
Can you report this upstream please?
Comment 2 Truls Asheim 2016-09-02 00:23:55 UTC
I was having similar issues, but for me, the problem also occurred even when using the Motif toolkit and additionally caused random segfaults when specifying a custom font using the xft font backend in an init.el containing only:

(setq default-frame-alist '((font-backend . "xft")
                            (font . "DejaVu Sans Mono-9"))

The culprit seems to be the cairo use-flag. Building emacs from git master using only the --with-cairo configure flag appears to be enough to reproduce the issues. Starting emacs -Q when compiled with cairo reproduces the window resizing problems mentioned in the this bug-report and running

emacs --no-site-file --no-site-lisp --no-splash --no-x-resources

with the aforementioned elisp statement in init.el makes the segfaults easily reproducible. For example by running M-x report-emacs-bug, M-x package-list-packages or simply by C-x C-f and trying to tab-complete a few folders.

The segfaults occur either in the string_hash function in fns.c or somewhere in libfreetype. I can post the GDB backtraces if anyone is interested, but as I'm not sure this is even a Gentoo related issue, I'm submitting the bug upstream.

But the bottom-line, for now at least, is that removing the cairo use-flag seems to make Emacs 25 work.

(In reply to Truls Asheim from comment #2)

Again, report this upstream, please. They are late in the release process for Emacs 25, but a segmentation fault might be severe enough still to be fixed before the release.

We can use this as a stopgap solution, but the underlying bug should be fixed.
Comment 4 Ulrich Müller gentoo-dev 2016-09-02 07:51:34 UTC
@rnddim, @Truls: Can you please post the value of the system-configuration-options variable in Emacs (C-h v system-configuration-options RET)? Or alternatively, attach the build.log?

Sure, here's mine, for 25.1_rc2 with the athena toolkit:

system-configuration-options is a variable defined in ‘C source code’.
Its value is
"--prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-dependency-tracking --disable-silent-rules --docdir=/usr/share/doc/emacs-25.1_rc2 --htmldir=/usr/share/doc/emacs-25.1_rc2/html --libdir=/usr/lib64 --program-suffix=-emacs-25 --infodir=/usr/share/info/emacs-25 --localstatedir=/var --enable-locallisppath=/etc/emacs:/usr/share/emacs/site-lisp --with-gameuser=:gamestat --without-compress-install --with-file-notification=inotify --enable-acl --with-dbus --without-gpm --without-hesiod --without-kerberos --without-kerberos5 --without-xml2 --without-selinux --with-gnutls --without-wide-int --with-zlib --with-sound=alsa --with-x --without-ns --without-gconf --with-gsettings --with-toolkit-scroll-bars --with-gif --with-jpeg --with-png --with-rsvg --with-tiff --with-xpm --without-imagemagick --with-xft --with-cairo --without-libotf --without-m17n-flt --with-x-toolkit=lucid --without-xaw3d GENTOO_PACKAGE=app-editors/emacs-25.1_rc2 'CFLAGS=-march=native -O2 -pipe' CPPFLAGS= 'LDFLAGS=-Wl,-O1 -Wl,--as-needed'"

And as an aside, I've been able to successfully use 25.1_rc2 with athena for a while now, so that at least works for me.
Comment 6 Ulrich Müller gentoo-dev 2016-10-15 11:00:34 UTC
There are issues with screen updates also with the Athena/Lucid toolkit, therefore I have masked the cairo flag in the base profile now:

+# Ulrich Müller <ulm@gentoo.org> (15 Oct 2016)
+# The --with-cairo option is considered as experimental by upstream
+# and causes problems with updating the X window, bug #592238
+app-editors/emacs cairo
+app-editors/emacs-vcs cairo
+
Comment 7 Ulrich Müller gentoo-dev 2019-11-22 13:17:19 UTC
I have lifted the cairo use mask for app-editors/emacs-vcs:27 some time ago, see bug 691830. At the same time, for app-editors/emacs the mask is restricted to slots 25 and 26, so it won't affect a future slot 27.

There is not much that we can do for slots 25 and 26 on the distro level, therefore closing.
