As always with Linux it depends on which distribution you're on but that hasn't been my experience at all with distributions like Ubuntu and Mint. I used Ubuntu back when the close, maximise and minimise buttons were on the top right and they moved them right from under me. I've tried to adjust to using flat packs but struggled with their very serious limitations while programs I rely on are no longer available in other package types. I have seen them see-saw between the horrible global menu and window menus, make wholesale changes to areas of the settings screen like display settings and mouse and trackpad settings. And I don't even know how many wildly different iterations of that horrible main menu application selector UI I have had to suffer through.
