alacritty: Crashes immediately because vsync could not be set up

Alacritty crashes without starting and complains about not being able to set up vsync (see logs below).

Reading other issues in this repo I can see that the vsync error is not a common one. If I manually start vsync using export vblank_mode=1 alacritty can be started. However, I don’t know what I’m dealing with and I do not want to mess up with that variable permanently (i.e. in more than one shell) unless I know it is safe to do.

System

OS:Ubuntu 20.04.4 LTS, running X11, GNOME Shell Version: alacritty 0.10.1
