I'm not sure if this bug should be filed against Xorg or against the kernel.

Consistent Xorg crash after upgrading to linux-image-6.18.5+deb14-amd64. Crashes on VT switch or screen lock. Crash occurs every time.

Downgrading to linux-image-6.17.13+deb14-amd64 fixes.

This was certainly a kernel bug. Upgrading to
linux-image-6.18.9+deb14-amd64 fixes it.
