smartdock leaves maximize close and other buttons after uninstalling

[ugly-custard]

I uninstalled smartdock but the minimize, maximize, close and the back buttons
that smartdock adds when in desktop mode still remain.
I've tried uninstalling, reinstalling and uninstalling again.

They are useful, but the buttons remain even when apps are fullscreened.
Which is annoying since the app is not utilizing the full screen anymore.

I can't find a way to remove them so if anyone has encountered this problem before,
please tell me how to remove them.

Talking about these btw if I wasn't clear enough

Since I dunno if this is happening because of some prop or something, and since I installed smartdock using this script, decided to ask here.
