panel kitten not able to open on non-focused output

[KaylaSolace]

Describe the bug
specifying an output that is not the currently active output causes a SIGSEGV Address boundary error
IE: specifying DP-2 works when DP-2 is focused, but SIGSEGVs if ran while on HMDI-A-1

To Reproduce
Steps to reproduce the behavior:

1. run kitty +kitten panel --output-name='DP-2' sh -c 'echo a' (or whatever your output name is)
2. See error

Screenshots
If applicable, add screenshots to help explain your problem.

Environment details

Post the back trace

[KaylaSolace]

is this correct?

Edit: so sorry, keyboard shortcut accidentally marked completed??

[KaylaSolace]

new to using GDB, ran gdb kitty, loaded the core, and ran backtrace to generate

Core was generated by `kitty +kitten panel --debug-rendering --output-name=DP-2 sh -c echo a'.

Dont use gdb, just generate the crash, then run

coredumpctl debug

and anser y when it asks if you want to download debug symbols as without that the backtrace is much less useful.

[KaylaSolace]

ah, I apologize.

In trying to recreate this, I realize I may be using the output name flag wrong, as it segfaults on invalid input (such as any string less than 4 characters) and just opens on the focused monitor with any string over 4 characters.

what is "output name" supposed to be? evidently HDMI-A-1, DP-2 etc are not correct, but having tried everything I can think of from the output of hyprctl monitors I cannot get it to do anything other than open on the currently focused monitor regardless of what the string provided is, given it is longer than 3 characters and shorter than 12
