Fontconfig regression bug

From fontconfig 2.17.1-1 to fontconfig 2.18, many of my GUI applications broke as well:

1. LocalSend only shows a black screen.
2. Wolfram Notebook crashes with Segmentation fault (core dumped).
3. OBS either fails to start or crashes when I click the Settings menu.

After downgrading back to 2.17.1-1, everything works normally again.

As a bonus, I can finally remove those Flatpak alternatives -_-.

Maybe it’s time to set up timeshift ?
