When disabled 'Ubuntu AppIndicators', clicks at minimize worked ok; but later, those clicks stopped working again even with all extensions disabled :/
Update: Discovered that I was clicking at an specific pixel that is not stollen by the icon tray.
I noticed that even the 'hover' mouse action over minimize-restore-close buttons, does not trigger.
