Comment 1 V Stuart Foote 2016-11-06 01:20:23 UTC
These issues moved from the HarfBuzz implementation issue bug 89870 as regressions, or just worse behavior than with the old layout engine:

bug 57672 - UI Combining diacritics breaking font preview in a dialo
bug 99351 - Square root of fraction doesn't display correctly
bug 103710 - Punctuation for CJK vertical layout using fallback is not rotating
bug 103725 - Wrong render of Math formula with HarfBuzz

Add reports of any new regressions again the HarfBuzz based common layout engine here.

Comment 3 OfficeUser 2017-02-20 19:34:18 UTC
I have added Bug 106111 since it is very likely caused by the new layout engine.
