Ubuntu Mate 24.04 Compiz not working Properly

[tkn]

You have @MaxTechnics to thank for that, it was his golden discovery that everyone was waiting for. Many mails have been spent on this subject.

Compiz as windows manager leads to empty desktop and missing menu bar (Wobbly windows wanted)

Might be late to the party. Going to Startup Applications, try disabling 'picom' (unchecking worked). This seemed to fix it for me. Running Ubuntu MATE 24.04.1 My guess is that compiz gets started, and then picom, which leads to both fighting as window manager. Hopefully that helps someone!
