Mate 桌面 reduced_resources

When I'm minimizing a window, I can see a black border effect (really ugly) show up. Is there a way to remove that?.

Effect i'm talking about.

I have a custom config file in ~/bin as explained in Compton - how disable fade effect? 2.

Try this guide here:

Dconf-editor is not included in Mate by default but you can just install it.
You can also try the option
org > mate > marco > general. Check "reduced-resources".
In addition to the above. I believe you dont see window contents when dragging if you do that one.
