[SOLVED] Xorg dumped core when moving windows between monitors

Hi, recently I've got this issue with Xorg crash when I move a window from one screen to another or when the screensaver starts. Also, some applications crash it on startup, such as Zoom and Discord (it might have some tricky windows adjustments on start). After the crash, I get my lightdm login prompt.
Here is the journalctl part with the dump

I thought it might be Nvidia driver / Linux core issue that will be solved but after 2 days and today's core update (5.13.4-arch1-1), no success.

I have a laptop with an nvidia card (driver - 470.57.02) and intel integrated. I don't remember exactly how the Optimus works, but I think it's the PRIME render offload.
Lightdm + XFCE (XFWM)

I have only the touchpad config in /etc/X11/xorg.conf.d/

Section "InputClass"
        Identifier "touchpad"
        Driver "libinput"
    MatchIsTouchpad "on"
        Option "Tapping" "on"
        Option "TappingButtonMap" "lrm"
    Option "NaturalScrolling" "true"
EndSection

Hi !
This is actually an issue with the latest xorg-server update.  There is an open issue that is currently investigated.
For now, the only solution is to downgrade the package as suggested.

Wow, thx. Downgrading xorg-server to 1.20.11-1 solved the issue.
