When I run Galaxy, it opens in fullscreen. I am unable to see the complete screen. I have tried several screen resolution fixes but they do not change anything. My screen resolution is the recommended 3840x2160. I have tried it on several other resolutions but it looks the same no matter what I select. I have to Alt-F4 to get out of it. No taskbar is available.
