crashes when one of the monitors goes disabled

[alembiq]

Thank you for making paperd, to me it's the best wallpaper solution from eight, I've tried on wayland.

I'm running Hyprland and it's clamshell configuration to disable notebook screen when I close my notebook.

                bindswitch --reload --locked lid:on output eDP-1 disable
                bindswitch --reload --locked lid:off output eDP-1 enable

with this configuration of wpaperd:

[any]
path = "/home/charles/nextcloud/Pictures/wallpapers"
duration = "30s"
mode = "center"
sorting = "random"
[eDP-1]
path = "/home/charles/nextcloud/Pictures/wallpapers/52204128092_76bb16feb4_k.jpg"

closing the notebook (disabling eDP-1 monitor) causes wpaperd to die :(

Hello and thank you for opening an issue! What is happening here is that the toolkit that handles wayland event (smithay-client-toolkit) is receiving events after the output is declared as dead, making wpaperd crash. At a first glance I'd say that it might be a race condition in hyprland, sending events that shouldn't be sent. Otherwise it might be smithay not updating its status. In case you are running version 1.0.1, can you please try with master version? In case it is still not working, can you please run wpaperd as the following and share the log? ```bash $ WAYLAND_DEBUG=client` wpaperd 2> wpaperd-wayland.log ```

Thank you @alembiq ! I will create an issue upstream as soon as possible.

[alembiq]

it seems that updating the smithay-client-toolkit to 0.19.2 should do the trick, see Smithay/client-toolkit#468

[danyspin97]

Thank you @alembiq, for opening an issue upstream. I have just updated the dependencies, now this bug should be fixed. Can you please confirm?

[alembiq]

i've just updated my system, and I can open and close my notebook without any crashes!
thank you
