[Bug 2017573] Re: Font hinting broken on Plasma 23.04


I know Ubuntu font underwent changes in 23.04 but comment #17 was
explicitly added to discharge any suspicion towards that change. It's
NOT only Ubuntu font that hints incorrectly when hinting is enabled. All
fonts that looked great in 22.04 are now horribly rendered in 23.04,
like e.g. Liberation Sans in #17.

It was a bad coincedence that I started this bugreport mentioning Ubuntu
font, since that was my default before migrating to 23.04.

I did a little search and my best guess now would be that this is a regression in libfreetype.
There is an explicit fix for hinting mentioned in the changelog for 2.12.1 which may have side effects not encountered before or that are now exposed by another change in 23.04? https://sourceforge.net/projects/freetype/files/freetype2/2.12.1/

Hmm... it seems kinetic was shipped with 2.12.1 as well, so that makes
it little less likely. Although the dfsg went from 3 to 4 in lunar?

  Font hinting broken on Plasma 23.04

Bug description:
  Just upgraded my laptops to Kubuntu 23.04 Lunar Lobster and hinting
  for all non-commercial fonts seems broken. I used to have decent if
  not perfect hinting on Ubuntu and Ubuntu Mono font, but now the only
  fonts that still hint correctly are Microsoft's Verdana and Tahoma
  etc. Not sure whether the devide is exactly along this line, but it
  stands out.

  Tried regenerating font cache (fc-cache -rv) but that didn't help.
