Description of problem:
After update to fontconfig-2.14.1-1.fc38.x86_64, fonts have red/blue shadows.
Therefore I guess the font hinting is somehow broken.

Version-Release number of selected component (if applicable):
$ rpm -q fontconfig
fontconfig-2.14.1-1.fc38.x86_64

How reproducible:

Steps to Reproduce:
1. This is most obvious in TB email from BZ, where the '|' pipe character has
shadows.
2.
3.

Actual results:
The characters has red/blue shadows

Expected results:
Characters without shadows

Additional info:
I have downgraded back to fontconfig-2.14.0-2.fc37.x86_64 for the time being.
