Bug on window when plugging monitor

[pvfreitassilva]

Every time I connect my monitor, if spotify is open on my notebook's screen then the window gets a cut on bottom and rigth. The buttons still works but I can't see them. Reducing the window size makes they appear. It seems Spotify gets limited by my notebook's screen resolution (1366x768). My monitor has 1440x900 resolution. It happens with other monitors too. I'm using Windows 10 64 bits, with Corel i7 processor, and Nvida Geforce 920.
