Dash to Dock crash every (or almost) time when I turn off the display or change the display output (to switch to the Raspberri Pi, which is connected to the same display). I can then restart (Alt-F2 + r), but it doesn’t work at all under Wayland (and it’s quite painful). Fedora 33 didn’t crash.
Tested (and reproducible) with two different displays.
For me Gnome without Dash to Dock (or similar) is not usable at all. Maybe it’s time for Gnome to add Dash display options to make Dash more user-friendly?
