Text jumbled after making an edit
I have a screen glitch which often appears when editing text:

In this instance, I changed the style of a paragraph, but many other edits cause the same glitch. If I scroll the error off the screen and back on, it resolves, so this would appear to be a graphics card issue. My computer is a Retina 5K mac, 27" late 2014 running High Sierra 10.13.6 and I am using InDesign CC version 13.1.
