I reported this issue on the GNOME Shell GitLab: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2908
Thanks to @vanvugt over there for the explanation, this appears to be the crux of the issue: > Although the simple act of logging to the disk can also cause such problems. > If you write anything to the disk more than once every 5 seconds then every 5 > seconds it will block while the kernel (ext4) flushes the journal. > So make sure you're not doing anything that causes regular log messages (run > journalctl -f). This means that there is a bug in both the AppIndicator extension and GJS. AppIndicator should not be erroring out when it encounters this, and GJS (which provides the native method for log and error output) should not write to the journalctl log this frequently to avoid huge journal flushes to disk. ** Bug watch added: gitlab.gnome.org/GNOME/gnome-shell/-/issues #2908 https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2908 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell-extension-appindicator in Ubuntu. https://bugs.launchpad.net/bugs/1849142 Title: appindicator extension slows down GUI spamming the log with "[AppIndicatorSupport-FATAL] unable to lookup icon ..." or "Impossible to lookup icon" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-appindicator/+bug/1849142/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
