I have noticed on some installations of MATE the windows manager comes with Picom compositor and on other installations it is not present.
What package do I need to install in order to provide PICOM?
Update :
Distros Are :
- Ubuntu-Mate 22.04 Jammy (AMD) PICOM was included
- Ubuntu-Mate 22.04 Jammy (AARCH64) PICOM included
- Armbian 23.02 Jammy + MATE (AARCH64) PICOM not included
As mentioned by guiverc the package is picom. Which did install and is supported on both ARM distros.
