I wanto to migrate from 16.04 unity to Mate 18.04. I am using the mate default Plank dock, through Pantheon interface, however I noticed an annoying bug with app icons locked in dock although they shouldn't. Examples:
1) Every time I configure the top panel, after I close the panel config window, the panel icon remains in dock and there's nothing I can do to remove it, besides login/logout
2) Same things for tray applications, e.g. I installed psensor which has a tray icon, if I minimize the psensor to tray it doesn't dissapear from dock.
Are there any solutions to this or is a plank inherent issue? I was thinking if there is a config where I can specify what applications should plank completely ignore and don't add them to dock. Is it possible?
Thank you and great work with UM!
