Dear Maintainer, With wayland and gnome, I have configured the shortcut Super+Alt+t to show/hide tilda with the command "tilda -T 0". Sometimes when I use the shortcut to show/hide tilda, a sequence of "t" is displayed as if the key remains pressed.
Maybe it's not a tilda problem. Sometimes I have the same problem when I switch desktop in gnome-shell (49.1-5) with Ctrl+Alt+left/right arrow.
