Changing font Hinting doesn't update font (Mint 20.2)

Original thread here.

Hello,

First, thanks for the hard work, still using XFCE since years without troubles (depicts some keyboard shortcut not working, but I don't know how to reproduce the problem).

Anyway, I have a bug, here how to reproduce:

• Go to Appearance/Fonts
• Change Hinting (to any value).
• Font rendering is not updated (the font rendering used in UI windows doesn't change).

I have to go tick "Custom DPI settings" and change the DPI value. As soon as I change the DPI value (by clicking on + or -), the font is updated.

Same problem with "Enable anti-aliasing" or "Sub-pixel order". Changing them doesn't update font rendering.

Keep the good work!
