If you use Ubuntu, you may want to change the radius of the corner effect for Dash-to-Dock in preferences, else you may see unpleasantly mixed radii in your dock.

Note: if the extension shows an error after updating, please make sure to restart your session to see if it persists. This is due to a bug in gnome shell, which I can't fix by myself.

For a more traditional experience, you may also want to use Tweak Tool to enable Windows > Titlebar Buttons > Minimize & Maximize.

Description

ddterm is unresponsive for ~5 seconds when switching between monitors

Steps to reproduce:

1. Set window-monitor to current
2. Move mouse cursor to another monitor (not the one where ddterm was shown previously)

[amezin]

gnome-shell[47314]: Spurious clutter_actor_allocate called for actor 0x56222c50f700/unnamed [ClutterActor] which isn't a descendent of the stage!
gnome-shell[47314]: Spurious clutter_actor_allocate called for actor 0x562234105760/unnamed [ClutterActor] which isn't a descendent of the stage!
...
gnome-shell[47314]: surface_state_changed: assertion 'wl_window->has_last_sent_configuration' failed

[amezin]

Maybe window geometry updates should cause delayed move/resize (i.e. from Meta.idle_add), not immediate

[magnetik]

Not sure if related but since a recent update (I guess), ddterm is frequently killed with signal 15 while it never happened before. My laptop is connected to two monitors and the kill always happen when the two monitors goes to sleep

[amezin]

@magnetik Please, create a separate bug report. And please try to collect logs when the issue occurs - i.e. start journalctl -f in GNOME Terminal/Console, and wait or make the monitors go to sleep.

[magnetik]

Will do, sorry if it added some confusion!

[amezin]

Not reproducible anymore - not sure what changed

[amezin]

Incomplete steps to reproduce:

1. Run a game using gamescope
2. Set window-monitor to current
3. Move mouse cursor to another monitor (not the one where ddterm was shown previously)

Persists until ddterm app is restarted. Maybe a Gtk 3 issue.

[amezin]

Switching the split mode also becomes slow.

And looks like it happens even when window size synchronization is removed completely... I.e. Gtk 3 relayout just becomes slow.

For me it originally happened when switching between monitors simply because they have different resolutions -> moving the window means resizing and re-layout.

Not sure if it can be worked around. Maybe just give up and focus on Gtk 4
