Using picom currently in stable, I’m not able to use the ‘dual_kawase’ blur method.
Here is my picom.conf:

Using manjaro-supplied picom, this is the error I get:
chewie@frigate:~$ killall picom
chewie@frigate:~$ picom -b --experimental-backends
[ 03/28/2021 08:27:13.634 parse_config_libconfig WARN ] Invalid blur method dual_kawase, ignoring.
And when I use picom I built from the git repo (following the build instructions on the repo):
chewie@frigate:src$ killall picom
chewie@frigate:src$ ./picom -b --experimental-backends
chewie@frigate:src$
