If you are using the single page display mode with half pages displayed in landscape with half page turns, there is an icon that will be visible at the bottom of the song overlay that lets you set the position of each half of the page. This can be used to prevent pages from being cut off in an undesirable fashion. If that is not sufficient, then I would suggest using a pedal to trigger page turns, and then you can set the pedal action to scroll the page 25% (or whatever amount lets you turn the page multiple times without losing any content. I would recommend using the "Scroll page down or turn page if at bottom" pedal action. 

You can also consider changing the display mode to "Vertical scrolling" with the page scaling mode set to "Fit Width". You will then be able to make full use of the screen, you can scroll in small segments by tapping, and you can optionally use the automatic scrolling feature to scroll continuously through the song.
