Dear Maintainer,
I updated my system yesterday, which caused the Vollkorn Regular font to stop working properly.
After the update, all text using Vollkorn was garbled (see the attached screenshot). Restarting the system solved the text being garbled, but now Vollkorn Regular appears bold, the same as Vollkorn Bold does. I haven't seen any non-Vollkorn font affected by this.
I tried switching back and forth in Cinnamon's configurations with not success.
Interesting is that the font files in /usr/share/fonts/truetype/vollkorn do appear to be correct. The thumbnails look fine, and when I open them they appear correctly; Except that if I open Vollkorn-Regular.ttf and then Vollkorn-Bold.ttf without closing the font-viewer (/usr/libexec/font-manager/font-viewer --gapplication-service) it still appears Regular even though the font-viewer clearly states it being the Bold font. The same thing works the other way around.
The issue with Vollkorn Regular appearing like Vollkorn Bold isn't limited to GTK applications. I tried switching Kate to use Vollkorn Regular and there it also looks like Vollkorn Bold.
I saw the fonts-vollkorn package being part of the last update, so this is why I am suspecting this package have caused the regression.
Greetings,
Julian Groß
