i noticed this bug probbably 3/4 years ago?
but i didnt report it, i guess i was lazy
ok so when go to Outline there are 4 options: None / Bordered / Shadowed / Both
here is 4 screenshots
None and Shadowed = correct
Boredered and Both = incorret
notice there is weird dots between letters they are not connected when selecting Boredered and Both
Arabic letters should be connected
i prefer Bordered over Shadowed its easy to read on light scenes
this bug is on iOS + Apple TV
i hope it gets fixed on upcoming 5.2 release!
