I'm not sure whether my bug is the same one or even related in its underlying cause. A program that I've helped write is exhibiting a constant failure to respond to mouse clicks in one subwindow that is implemented by an embedded mozilla browser window inside a Mono C# program. Keyboard input to that window works fine, but mouse clicks on a button are ignored. This appears to be related to the main form and controls down to the one hosting the mozilla browser all receiving WM_KILLFOCUS messages shortly after receiving WM_FOCUS messages when first clicking inside the window. Other desktop environments / window managers do not have this behavior in either ignoring the mouse clicks or receiving the spurious looking WM_KILLFOCUS messages. (For example, Unity, Cinnamon, XFCE, LXDE, and MATE all work fine. Unfortunately, none of them are the default for Ubuntu 18.04 which is what many of our users are upgrading to.) The program can be found at https://github.com/BloomBooks/BloomDesktop for what it's worth. I know it's an unusual mix of C#, TypeScript, Pug, Less, etc. but it works fairly well under Ubuntu 16.04 with Unity or Cinnamon and under Ubuntu 18.04 with Cinnamon. It's quite frustrating for it to have this bizarre bug under the default desktop environment for Ubuntu 18.04.

I can use alt-tab to cycle windows and can still type into already- active textboxes in windows, but I cannot click within the windows, and the mouse is not picked up at all by the windows. I can open the alt-f2 "run command" dialogue, but cannot type into it. The workaround I'm using is to open terminal (ctrl-alt-T) and run "gnome-shell -r", and restarting that command every time I have the problem again. Please ask if there's anything I forgot to mention. ADDITIONAL: The error tends to happen randomly, but it seems to happen upon opening a new window, changing windows, closing windows, or opening the activities pane (whether a change of window is thus instigated or not) ADDITIONAL 2: (sorry, it's early) The other workaround is to log out and to log in again, but that is also less than ideal ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: gnome-shell 3.6.3.1-0ubuntu6 ProcVersionSignature: Ubuntu 3.8.0-22.33-generic 3.8.11 Uname: Linux 3.8.0-22-generic x86_64 ApportVersion: 2.9.2-0ubuntu8 Architecture: amd64 Date: Sun May 19 07:02:18 2013 DisplayManager: gdm GsettingsChanges: b'org.gnome.desktop.interface' b'clock-show-date' b'true' b'org.gnome.desktop.interface' b'clock-show-seconds' b'true' b'org.gnome.desktop.interface' b'document-font-name' b"'Sans 10'" b'org.gnome.desktop.interface' b'font-name' b"'Cantarell 10'" b'org.gnome.desktop.interface' b'monospace-font-name' b"'Ubuntu Mono 12'" InstallationDate: Installed on 2013-05-04 (14 days ago) InstallationMedia: Ubuntu-GNOME 13.04 "Raring Ringtail" - Release amd64 (20130424) MarkForUpload: True ProcEnviron: LANGUAGE=en_GB:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_GB.UTF-8 SHELL=/bin/bash SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1181666/+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
