And an update:  I've discovered the problem previously reported here (missed 
this for some reason when searching earlier):

https://tex.stackexchange.com/questions/311041/subscript-and-superscript-in-lyx-leave-large-gaps-in-onscreen-editor
 
<https://tex.stackexchange.com/questions/311041/subscript-and-superscript-in-lyx-leave-large-gaps-in-onscreen-editor>

-- with a reference to this bug report: https://www.lyx.org/trac/ticket/10177 
<https://www.lyx.org/trac/ticket/10177>

Is there an approved way to add my own "please fix this" to that bug report 
from two years ago?
