Using complex Thai fonts GeckoView must to enabled so they render correctly. See Mark 1:1 correctly rendered below.
But if a Verse on Image is created the rendering is as it would be without GeckoView.
Hopefully a way can be found to enable GeckoView to render the text in Verse on image. You can download this app to see this issue. https://play.google.com/store/apps/details?id=lnb.nt.w.inte.aud.rg
