I tested by applying the patch against the current Ubuntu Xenial release version of the metacity package (metacity_3.18.4-0ubuntu0.3). I can confirm the patch fixes the regression (it allows me to drag my Firefox and Thunderbird windows above the top of the screen.) So far, I have encountered no new regressions.
I also tried building metacity git master, but ran into several unmet dependencies (newer versions of gtk+/glib than what I have installed), so I was unable to complete that test.

When I attempt to do so, the window snaps downward along the y-axis so that the titlebar aligns with top of screen. Other applications such as gnome-terminal do not seem to be affected. I ran git-bisect on metacity, and narrowed the regression down to this commit: https://github.com/GNOME/metacity/commit/90b36abebdf69be0abaec4015d01e46296f6f5d6 commit 90b36abebdf69be0abaec4015d01e46296f6f5d6 Author: Alberts Muktupāvels <alberts.muktupav...@gmail.com> Date: Fri Apr 3 23:30:20 2015 +0300 window: add a meta_window_get_titlebar_rect Based on mutter commits: https://git.gnome.org/browse/mutter/commit/?id=3a0af0faaebb1af75925c70ad98e73c61e57639b https://git.gnome.org/browse/mutter/commit/?id=ac099343dab7b5048ce242958c454c55d1924902 ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: metacity 1:3.17.2-4ubuntu1 ProcVersionSignature: Ubuntu 4.2.0-16.19-generic 4.2.3 Uname: Linux 4.2.0-16-generic x86_64 ApportVersion: 2.19.1-0ubuntu3 Architecture: amd64 CurrentDesktop: GNOME-Flashback:Unity Date: Thu Oct 22 13:35:02 2015 InstallationDate: Installed on 2014-09-22 (394 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) SourcePackage: metacity UpgradeStatus: Upgraded to wily on 2015-10-22 (0 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1509031/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
