Thank you, Daniel, very interesting info. I noticed some strange behavior/stats when moving the terminal with the log between the internal and external displays. Maybe it's normal but it felt weired.
The log output without the CLUTTER option yields this: ~$ journalctl -f /usr/bin/gnome-shell юни 11 08:48:29 hristo-Inspiron-15-7000-Gaming gnome-shell[2083]: DING: Detected async api for thumbnails юни 11 08:48:30 hristo-Inspiron-15-7000-Gaming gnome-shell[2083]: DING: GNOME nautilus 42.1.1 юни 11 08:48:39 hristo-Inspiron-15-7000-Gaming gnome-shell[2083]: ATK Bridge is disabled but a11y has already been enabled. юни 11 08:49:34 hristo-Inspiron-15-7000-Gaming ubuntu-appindicat...@ubuntu.com[2083]: unable to update icon for software-update-available юни 11 08:49:34 hristo-Inspiron-15-7000-Gaming ubuntu-appindicat...@ubuntu.com[2083]: unable to update icon for livepatch юни 11 08:50:35 hristo-Inspiron-15-7000-Gaming gnome-shell[2083]: meta_window_set_stack_position_no_sync: assertion 'window->stack_position >= 0' failed юни 11 08:52:42 hristo-Inspiron-15-7000-Gaming gnome-shell[2083]: libinput error: client bug: timer event9 debounce short: scheduled expiry is in the past (-26ms), your system is too slow юни 11 09:07:17 hristo-Inspiron-15-7000-Gaming gnome-shell[2083]: libinput error: client bug: timer event9 debounce short: scheduled expiry is in the past (-26ms), your system is too slow юни 11 09:12:29 hristo-Inspiron-15-7000-Gaming gnome-shell[2083]: libinput error: event9 - Logitech G603: client bug: event processing lagging behind by 33ms, your system is too slow юни 11 09:12:29 hristo-Inspiron-15-7000-Gaming gnome-shell[2083]: libinput error: client bug: timer event9 debounce short: scheduled expiry is in the past (-21ms), your system is too slow -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1970291 Title: [nvidia] Secondary monitor performance is slow on an Nvidia hybrid system in Wayland sessions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1970291/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
