I am still getting this bug with the proposed version. Ubuntu 20.04 on a Lenovo machine.
I hope I updated correctly, I followed the instructions linked above to activate the "proposed" repository and installed the package with "sudo apt install mutter/focal-proposed", then deactivated the "proposed" repository and rebooted my machine. For the record, "dpkg --status mutter" shows "Version: 3.36.4-0ubuntu0.20.04.2", so I think I did it correctly. I did not touch gnome-shell. "gnome-shell --version" shows 3.36.3. I used the touchscreen and triggered the bug after just a few minutes. gnome-shell crashed and some familiar messages were dumped in the syslog: Aug 11 10:51:24 c930 gnome-shell[5197]: Object Meta.BackgroundActor (0x55be2f3b63f0), has been already deallocated — impossible to access it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs.
