Since 5.3b1 on OSX the UI text (in dialogs, toolbars, status bar etc.) is rendered differently, also with another narrower font (AFAICS).
I am not sure if that is a direct consequence of using HarfBuzz or of some other change.
But the UI is much less readable; it seems that with 5.2.x it was rendered in system font and had also much less smear in rendering the UI text.
I am attaching the screenshot of the same dialog (in 5.3b2 the same dialog is also rendered much bigger, but that might be another issue).
Steps to Reproduce:
1. Open LibreOffice
2. Open any dialog etc.
Rendered text in 5.3.x UI is very narrow, smudged, less readable on OSX.
UI as readable or better readable than in 5.2.x on OSX.
