Product and version
FileMaker Go_iPad 14.0.4
OS and version
Button bar dividers appear to be wider than the borders even though both are set to the same pixel width.
FMGo_iPad 14.0.4 renders the borders as 1px and the dividers as 2px on iPad 2
How to replicate
Create a layout with Enlightened Touch theme.
Create a button bar, leave the style as Default.
Set the border to be visible and give it the same visual attributes as the dividers ( 1px , #5C5C5C ).
Load the file onto an iPad and view.
