output toggle on a bindsym happens twice.

[freed00m]

When changing output on a bindsym, the entire action happens twice. Renders toggle action on display impossible without arbitrary sleep workaround.

• Sway Version: 1.5.1

• Debug Log: http://ix.io/7y2

• Configuration File:
  https://git.sr.ht/~freed00m/dotfiles/blob/12f4594c07a2a29967134e127ff9a9694a2dfb5d/.config/sway/config

• the troublemaker bind is here

• https://git.sr.ht/~freed00m/dotfiles/tree/12f4594c07a2a29967134e127ff9a9694a2dfb5d/item/.config/sway/config_non-atos-Laptop#L8

I could not find the default sway config, I can retest if requested.

Description:

• eDP-1 is my laptop's display.
• no kanshi is running.
• When I do bindsym for output eDP-1 toggle|enable|disable the entire bind gets executed twice.
• It happens even using exec swaymsg or moving the swaymsg command to a script exec sh -c "reload.sh"

The problem can be mitigated by a short debounce "sleep 0.1", in that case the bindsym succeeds and get executed only once.
I suspect the toggle happens so fast the button key release gets also recognized as a new press.

The model is HP Zbook 15 G3 running i915 graphics with nouveau being blacklisted and not loaded in the kernel.

Does --release help?

[freed00m]

Yes, it does. :)

Don't fully understand why it's needed when manipulating outputs though.

Feel free to close 👍🏻

I think the input devices are re-configured when the output configuration changes, in case there is an input-to-output mapping. And re-configuring a keyboard reloads the keyboard layout thus re-executes the currently pressed bindings.

So, this behavior could probably be avoided in Sway, if someone wanted to.

So this is a bug with keyboard events happening twice on reloading the keyboard layout?

The same happens when the screen is dpms off and I press any binding and the display wakes up. I am unsure if that is the same, but it is not a mapping causing it, it is the automatic wake-up on any input event, so I cannot use --release for all of my bindings to fix that.
