alacritty: Unable to launch alacritty with Fullscreen startup mode on Wayland

Just to make it clear, the same issue is relevant under sway. So I guess it’s just a general issue here, rather than GNOME specific.

@chrisduerr Right on

@sjug What’s your sturtup_mode in a config, It’s Fullscreen, right? So try setting it to Windowed and then toggling fullscreen.

@kchibisov Yes you’re right, changing it to windowed allows it to start (and not panic). Then toggling fullscreen works fine.

Oh yeah, this only seems to crash when executing current_monitor which is not done by the examples by default. You’ll have to run cargo run --example fullscreen in the glutin examples and then press F to toggle it to fullscreen. That should crash it, right?

@chrisduerr When I run that command it asks me to select a monitor, so I select my only monitor 0. Then it starts the example in full screen and I can toggle it with F back and forth no issue.

Would you mind providing some info about your setup, like multiple monitors or smthing like that, and are you running alacritty with default config?

I’m using an AMD Vega 64 GPU, do I need to set any debug flags on compile?
