<pre>With Gtk+ 3.x applications running with a wayland Gdk backend I recently
discovered an issue which exits applications in rare cases. They happen
while/after showing a menu. Right before the application exits, it prints this
warning
Gdk-WARNING **: Error 71 (Protocol error) dispatching to Wayland display.
from gdk/wayland/gdkeventsource.c:197. There are 2 cases I can reproduce:
1. In LibreOffice Impress, when using the "View" menu, in some cases it just
exits after printing the warning added above.

Backtrace: <a href="https://bugzilla.redhat.com/attachment.cgi?id=1172226">https://bugzilla.redhat.com/attachment.cgi?id=1172226</a>
2. Firefox builds with Wayland Gdk backend behave similiar on showing any menu
(!)

Note that this doesn't work with default Firefox builds because they enforce
using x11 as Gdk backend on linux. You have to use the builds from
<a href="https://copr.fedorainfracloud.org/coprs/stransky/firefox-wayland/">https://copr.fedorainfracloud.org/coprs/stransky/firefox-wayland/</a> instead. See
this mailing list thread for details:
<a href="https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/54P3DQEOHXJQNUPUMHLA2GSQCWU4ZKXE/">https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/54P3DQEOHXJQNUPUMHLA2GSQCWU4ZKXE/</a>
I'm reporting this here because it happens in 2 very different applications and
because a LibreOffice developer commented this would be an issue in Gtk+ in
<a href="https://bugzilla.redhat.com/show_bug.cgi?id=1343752#c10">https://bugzilla.redhat.com/show_bug.cgi?id=1343752#c10</a>
Despite using gnome+wayland heavily, this bug hasn't occurred to me anywhere
else before so I guess it is either recently introduced or due to the special
way how Firefox and LibreOffice use Gtk+.</pre>
