Black Diaganol Lines in Edit Window/w Range Tool

Hello, I would like to know how to stop the Black Diagonal, line that show on the Waveform when I select the range tool, This line seem to show up as I hover the mouse over the Image. And when u select a range, then it goes away. This type of view make it hard for me to see my edits when I’m zooming in close. Anyone know how to turn this edit view function off, Please.
Thank You
