Unity Dynamic Font atlas errors

Hello,

It looks like the our Unity Dynamic Font is breaking on 4:3 at higher resolutions for our Mobile Game. We haven't had any issues with 16:9 on high resolutions, just at 4:3. Does anyone know of a solution that isn't "change all the text in your game to Text Mesh Pro"?

Our team is currently building on 5.6.1p1 and deploying to Android, iOS, and webGL. This issue is only happening on an iPad Mini and iPad Pro so far.
