Fix crash when new output added #73

Closed mstoeckl closed 3 months ago

mstoeckl commented 3 months ago

Calling get_buffer_size on a newly created swaybg_output, before a config is assigned to a swaybg_output, is unnecessary and yields a null pointer dereference.

To reproduce the crash: open a nested instance of sway, run swaybg , and call swaymsg create_output.
