I apologize if this is not the right place to report this issue. Marco with compositing seems to be broken on Linux Mint 20 Mate with AMD Radeon RX 550 GPU (the 4 GB version) and DVI-D output. It happens even on the live iso that boots right to the corrupted screen.
See this screenshot:
I have tried different compositors like Metacity + Compositing and Marco + Compton and they all worked fine.
Marco + Compositing worked fine on old Nvidia GPU (with both Mesa and proprietary drivers), but not on this new AMD one.
Unfortunately, I was not able to get any relevant system logs.

edit: I have also reported it upstream.
