Regression?

Definitely a regression - something broke after update (requires bisect)

Description

When disconnecting monitors from Hyprland, it now segfaults, after an indeterminate amount of time.

How to reproduce

1. Unplug monitors or activate KVM switch without edid emulation (dumb switch effectively pulling the plug)
2. Hyprland will crash at some point.

Checklist of files to include below

• Hyprland config - hyprctl systeminfo -c (always include)
• Crash report (always include in case of crash)
• Video (always include in case of a visual bug)
• Logs (might contain useful info such as errors)

Additional info & File uploads

I've tried to bisect, however it is inconsistent. If absolutely needed I will attempt to bisect this weekend. Attached is a full backtrace from the coredump. Hyprland did not produce any crash reports.

I am also getting this issue when waking from suspend. I'll try to bisect

This seems to be caused by a layer surface being created on a non existent monitor, which prevents the full constructor from running, so when the layer surface is destroyed, accessing the fade in animation segfaults because it is null.

fixed by #9247

Still get a segfault on 47.2, at a different location. Should I open a new issue, or should this one be reused?

that one comes from split-monitor-workspaces, not hyprland.

@vaxerski same crash without plugins.

That seems to have fixed it. Thank you!
