System Information
Operating system: Linux-6.1.1-zen1-1-zen-x86_64-with-glibc2.36 64 Bits
Graphics card: Mesa Intel(R) Iris(R) Plus Graphics (ICL GT2) Intel 4.6 (Core Profile) Mesa 22.3.1
Wayland compositor: Sway
Monitor setup:

1920x1200 screen at 0,0 with scale=1
2256x1504 screen at 1128,1200 with scale=2

Blender Version
Broken: version: 3.4.1, branch: makepkg (modified), commit date: 2022-12-20 08:50, hash: ef9ca44dee
Worked: Unknown

Short description of error
Blender segfaults (= crashes) when disconnecting the monitor.

Exact steps for others to reproduce the error

Open Blender, ensuring it is using Wayland and not Xwayland
Disconnect the monitor (can also be done using swaymsg output DISPLAY-IDENTIFIER disable)
See Blender segfaulting

Doesn't seem to rely on the currently open file, it also works when the welcome dashboard is open.

Backtraces

This is the backtrace I got using coredumpctl debug and then bt on my machine:

On the other hand, I've asked a friend of mine running a triple-monitor AMD GPU setup (but also running Sway on Arch) to reproduce this, and they got this backtrace instead:

This looks to be a bug in wlroots, reported: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3559

Although as this doesn't crash with SDL or GTK, it may be worth supporting it.
