It seems to be related to the cursor position not properly reflecting the displayed text wrapping. For instance, when displayed item text wraps to the next line, in some circumstances the cursor position acts as if the text has not wrapped and is still being added to the first line.
Sometimes on the second line the cursor is still behind, or ahead, of the actual location where text is being inserted, as if the cursor location is based off a different text wrapping than is the displayed text.
I seem to recall that the input text and display text are two separate elements so maybe they are wrapping differently for some reason. I wonder if it could have something to do with modifying the font face, size or style in the Display Settings Basic or Layout sections. For the record, I use Segoe UI 14. Not sure if my current Layout modifications are different than the default for anything that would affect this.
