MuseScore 3 doesn't seem to conform to my aspect ratio

I just started with MuseScore 3 after spending a bit of time with MS2. However none of the windows in MS3 seem to fit my screen resolution (1280x720)-- Most of the windows appear with the confirm buttons below the taskbar, so I can only click it by aligning it to the side of the screen with Windows Key + Left/Right arrow, and I can't use the mixer for what I want at all because I can't see the bottom half of it, as it extends past the taskbar. Is there anyway I can resize the windows to be a more comfortable fit?
