Font bug in 2018

Recently I discovered a font bug in CD 2018 on Win 10 1809: many of my fonts display incorrectly in Draw. But if I convert them to curves or switch the view to wireframes the font is displayed as expected. There are no such problems in other programs (Adobe, MS Word...). Recently I opened my old cdr from February and found that one of the fonts used there displayed incorrectly. But at the time of working with the document there were no problems. So I think this bug is relatively recent. Maybe some Windows updates are the cause.
Any thoughts?
