Resizing some windows causes SEGFAULT when using Wayland and nvidia proprietary drivers

Here's the original issue https://gitlab.gnome.org/GNOME/mutter/-/issues/1336

Bug summary

Resizing windows running on the XWayland compatibility layer causes a segfault and a full crash of gnome-shell. Notably >Chromium based applications (chromium, VSCode, and Brave Browser) are affected. Any window created with the >GDK_BACKEND=x11 environment variable set also cannot be resized without crashing.

Steps to reproduce

1. On a system with an Nvidia graphics card, install nvidia proprietary drivers (nvidia and nvidia-utils packages on Arch).
2. Ensure kernel modesetting is enabled (add a file in /usr/lib/modprobe.d/ containing options nvidia-drm modeset=1). Gnome will run with X11 backend if modesetting is not available.
3. Resize a Chromium window or any window created with the GDK_BACKEND=x11 env var set.

My Setup

Arch Linux kernel 5.8.0

Gnome Shell version 3.36.4

Nvidia Driver 450.57
