Sorry, the Submit button is directly next to the "Add Attachment" button for some reason :|

We recently came to the conclusion that VTE's scrollbars have a similar problem due to an out-of-band gdk_window_process_updates() call processing the expose event, see the last few comments of https://bugzilla.gnome.org/show_bug.cgi?id=771899 .

I've tried looking why that call exists in the eog source in the first place but it was added before the project even moved to git and just like in VTE, that reason seems long gone.

Yes, I was wondering about that one too lately as it started showing up in the deprecated API list. The non-updating scrollbars were "fixed" with a workaround in GTK.

    gtk+ will process the updates itself once the time comes.

This problem has been fixed in the unstable development version. The fix will be available in the next major software release. You may need to upgrade your Linux distribution to obtain that newer version.
