This applies to the Devenagari (Hindi, Sanskrit and some other languages) script.
In review the top of the letters is cut off, sometimes making an important dot or stroke invisible or less visible.
(I don’t have a pic now - because the time is so fast; image to be posted later)
Cut after giving the wrong answer; in this picture top of the curve is cut off:
Example below: a dot should have been approximately where the red dot is drawn:
Top of letter cut off when selected in multiple choice. See image below. In the red circle an stroke and a dot should be visible, but as they are cut off, they are hard to recognize. They are though visible in the option below number 4 (blue circle; because the timer requires to make the screenshot really fast, the bottom of this word is not fully copied, but it looked fine)
Exception: The top the letters not or less cutt off when UNselected.
I think this has been reported for the Memrise site as well; but on the Decks I noticed a difference: when UN-selected, the letters are wholly visible.
