One day I discover Ubuntu Mate Desktop user-interface better than Linux Mint.
The main issue Ubuntu Mate's UI is better than Linux Mint.
So I shift to Ubuntu Mate.
Today I notice the global menu does not perfectly.
For example, Global menu works all kind of browsers and media player.
But another software not.
Please help me brother.
I love Global menu on MenuBar.
Have you uninstalled it purged it and reinstalled it, if youneed help with doing that I can help, that's the only thing I can think of besides a dconf setting
If your using command line you should go "apt search mate global menu", "sudo apt remove (the exact name of the global menu that is installed), then "sudo apt purge (exact name). Sorry I can't give you the exact name I'm not at my computer
When people refer to purging, they usually mean to use apt purge or apt remove --purge (both valid) to remove configuration data associated with an application, as well the program itself.
apt remove by itself doesn't remove configuration data. This is done in case you happened to want the program back and have everything as it was prior to removal. If the intention is to start fresh with an application, you would purge it, not just remove it.
Sorry I cannot help better than this, I was only answering the immediate question with a definition of terms. I am also rather uncertain how you can fix this issue, personally. The best way I found to figure out what one does wrong is to remember what one did in the first place to get there.
