Cagebreak crashes with mpv --fullscreen

[sodface]

Running the latest development branch of Cagebreak on Alpine with wlroots 0.17.2. I don't normally run mpv with --fullscreen but I was working on something and added it for troubleshooting and was surprised that it caused Cagebreak to crash back to the tty.

Steps to reproduce:

This works:

mpv --idle --load-scripts=no --force-window

And just adding --fullscreen causes a crash:

mpv --idle --load-scripts=no --force-window --fullscreen

I tested starting the same mpv command with Cage, both from tty and from within a nested session inside of Cagebreak and both of those work fine.

Hi sodface

Thanks for reporting this! We can indeed reproduce this and have
uploaded a fix to the development branch. Can you check whether this

Ran into this problem with emacs and was about to submit a patch with the same fix that is on development branch... so also confirmed fixed.
