Bend "fraction" may have illegible text.
When Bends are less than "Full" MuseScore displays a fraction above the Bend's arrow. Under certain circumstances the fraction's characters appear to overlap. Whatever the cause, the text is illegible. This is demonstrated in the last line of the attached score—and it's better illuminated by illustration there than by description here.
Although bend plays correctly, this is a small show stopper as I can't publish a score that contains garbled text.
