Since upgrading to 20.04 and switching to Wayland, Gnome terminal occasionally crashes. I interpret the corresponding logs to mean that it’s actually Wayland that fails to do something in the background, which then takes down Gnome terminal:<\/p>\n

I have yet to nail down the precise circumstances, as this has (so far) been somewhat rare, having occurred perhaps once or twice a week.<\/p>\n
Since the log mentions pointer, I should perhaps mention that I’ve set `org.gnome.desktop.wm.preferences` > `focus-mode` to `mouse`.
