Description of problem: When running the GNOME Wayland session dragging gnome-terminal windows from one workspace to the next or between monitors in overview mode causes a fatal lockup that requires a hard-reboot, pressing the power-button. Version-Release number of selected component (if applicable): gnome-shell 3.18.3-1.fc23 Steps to Reproduce: 1. Start a new GNOME on Wayland session. 2. Launch some new GNOME Terminal windows. 3. Open up the Activities overview mode and move a terminal from one workspace or monitor to the other. Actual results: Total and complete system crash, can't even access TTY's and requires a hard reset to fix. Expected results: The Terminal window moves normally and everything goes smoothly. Additional info: I'm seeing this in the journal: Dec 31 01:18:58 user.local gnome-shell-wayland.desktop[2216]: (gnome-shell:2216): GLib-GObject-WARNING **: gsignal.c:2634: instance '0x55a5293c1ee0' has no handler with id '56954' Dec 31 01:18:58 user.local gnome-shell-wayland.desktop[2216]: (gnome-shell:2216): GLib-GObject-WARNING **: gsignal.c:2634: instance '0x55a5293c1ee0' has no handler with id '56955' Dec 31 01:18:58 user.local gnome-shell-wayland.desktop[2216]: Gjs-Message: JS LOG: _onFocus [object instance proxy GType:MetaWindowX11 jsobj@0x7fdcc56669a0 native@0x55a5293b5660]
This happens only when you move a maximized window, right? In that case it's https://bugzilla.gnome.org/show_bug.cgi?id=757676 .
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Upstream bug is closed and marked as fixed. I can confirm the fix in Fedora 25.
