Datagrid Scrolling

[andrew at midwestcoastmedia.com]

I agree, and my clients have confirmed, that scrolling with dg2 is  
jerky compared to dg1. This isn't as noticeable when scrolling at a  
fast rate, but very evident at slower speeds.

As Sannyasin mentioned, I can't go back to LC8 due to lack of iOS12  
compatibility (smooth scrolling is important, but not at the cost of  
the app not even launching).
