Hi, I am a contributor to the Tails project (https://tails.boum.org/), a live system aimed at preserving its users' safety, privacy and anonymity, focusing on ease of use for non-technical users. To give you an idea of the impact of the problems I'm asking for help here, we're talking about a system that is started more than 17,000 times a day.
I believe that some of you have met one of my team-mates at GUADEC 2015, who raised your names when I asked him who I could ask for help; hence this email :) We are about to release Tails 2.0 in a week. It will be our first release based on Debian 8 (Jessie), and more to the point here, our first release that includes GNOME Shell as the default (and only) desktop environment. Woo! There's a glitch though: during the beta and RC phases, many testers reported to us serious bugs with how icons in the top-right tray are displayed. Probably relevant is the fact that we include the topIcons extension (because not all the important status icons have been migrated to more modern GNOME technologies yet). But not only icons moved by topIcons to the top-right tray are affected. TBH, I personally came to the conclusion that the bug most likely lives in the topIcons extension. I can very well understand if you see it as none of your business for this reason, and I have reported it to this extension's author already. Still, we're in a hard place on our way to ship GNOME Shell right now, because sadly, nobody on our team has the skills to debug this problem, so we help from any skilled people would be much appreciated. The symptoms we see are: * Widgets in the top-right tray are somewhat narrowed (to their arrow, with a dot instead of the expected text); I've seen this happen at least for the date/time and the ibus menu icon: https://labs.riseup.net/code/attachments/download/1186/new-session.png https://labs.riseup.net/code/attachments/download/1180/1.png https://labs.riseup.net/code/attachments/download/1181/2.png https://labs.riseup.net/code/attachments/download/1182/3.png https://labs.riseup.net/code/attachments/download/1183/4.png * The clickable area and the icon of a widget moved by topIcons are not at the same place. For example, nothing happens when I click on the Florence icon, but Florence appears when I click elsewhere (on the left of the OpenPGP Applet). This screenshot shows what is the clickable area for Florence at this point: https://labs.riseup.net/code/attachments/download/1173/clickable%20area.png Enabled extensions: * Classic mode extensions: [email protected] and [email protected] * topIcons v28 * a custom Tails extension called [email protected]: https://git-tails.immerda.ch/tails/tree/config/chroot_local-includes/usr/share/gnome-shell/extensions/[email protected]?h=testing Other possibly relevant information: * We run GNOME Shell 3.14.4-1~deb8u1 in Classic mode. * The ISO image for Tails 2.0~rc1 can be downloaded from https://tails.boum.org/news/test_2.0-rc1/ — it's a live system, so you can try it out in a virtual machine, after dd'ing it to a USB stick, or burning it to a DVD. * I don't seem to be able to reproduce these bugs with an ISO that has the topIcons extension disabled. It seems that a loaded (or just slow) system exposes the problem more often than a powerful and idling system. * I've seen similar bug reports online elsewhere: https://extensions.gnome.org/extension/495/topicons/ https://www.reddit.com/r/archlinux/comments/2g06t7/icons_disappearing_from_notification_tray_using/ * In an environment (Spice/QXL/QEMU VM) where I can dynamically change the display size & resolution, making the display way bigger fixes the bug, and reverting to the initial display size reverts back to the problematic initial state. * There is one error in the logs that I only see when the bug happens: gnome-session[2343]: (gnome-shell:2871): GLib-GObject-WARNING **: /build/glib2.0-EvFudu/glib2.0-2.42.1/./gobject/gsignal.c:2579: instance '0x94b20f0' has no handler with id '32170' It refers to https://sources.debian.net/src/glib2.0/2.42.1-1/gobject/gsignal.c/?hl=2501#L2579 When this happens, I also see: gnome-session[2003]: (gnome-shell:3042): Gjs-WARNING **: JS ERROR: TypeError: parent is null gnome-session[2003]: onTrayIconRemoved@/usr/share/gnome-shell/extensions/[email protected][email protected]/extension.js:115 * Another piece of logs that we (sometimes) see when the problem happens: gnome-session[30034]: (gnome-shell:30263): Gjs-WARNING **: JS ERROR: TypeError: parent is null gnome-session[30034]: moveToTop@/usr/share/gnome-shell/extensions/[email protected][email protected]/extension.js:135 gnome-session[29844]: (gnome-shell:30074): Clutter-WARNING **: Attempting to add actor of type 'ShellTrayIcon' to a container of type 'ShellGenericContainer', but the actor has already a parent of type 'ShellGenericContainer'. * The https://github.com/wincinderith/topicons fork has changes in areas that might be relevant to the problems we see. We've not tested it so far. Is there any information you need from us to debug this problem? I'm sure those of us who see this problem would be glad to test patches aimed at fixing it. Please don't hesitate forwarding this message to anyone you think might want to give us a hand.
