Originally reported here: https://bugreports.qt.io/browse/QTBUG-71671 From xtrace output I see that gnome re-parents the window to the root window and mistakenly adjusts 'y' coordinate. There are no plausible reasons why WM should change window's coordinates when unmapping. 000:>:01c6: Event (generated) ConfigureNotify(22) event=0x02a00005 window=0x02a00005 above-sibling=None(0x00000000) x=600 y=526 width=200 height=200 border-width=0 override-redirect=false(0x00) 000:>:01c6: Event ReparentNotify(21) event=0x02a00005 window=0x02a00005 parent=0x0000011b x=600 y=526 override-redirect=false(0x00) Where: root window id = 0x0000011b 0x02a00005 = window which coordinates before calling unmap are x=600, y=600 ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: gnome-shell 3.28.2-0ubuntu0.18.04.1 ProcVersionSignature: Ubuntu 4.15.0-36.39-generic 4.15.18 Uname: Linux 4.15.0-36-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CurrentDesktop: GNOME Date: Wed Nov 21 15:33:14 2018 DisplayManager: gdm3 ExecutablePath: /usr/bin/gnome-shell GsettingsChanges: b'org.gnome.shell' b'enabled-extensions' b"['[email protected]']" b'org.gnome.shell' b'favorite-apps' redacted by apport b'org.gnome.desktop.interface' b'gtk-im-module' b"'gtk-im-context-simple'" InstallationDate: Installed on 2018-08-16 (97 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1804467/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
