When selecting fonts, font weight varies

[Fernando Fernandez]

I'm not sure this is a teak problem or a generic font display problem. The fact is that I'm trying to select a comfortable font using gnome-tweak-tool and the font picker doesn't always display the fonts in the same way. I attach two examples, taken with a couple of seconds delay. One is the font picker for "Interface" and the other is for "Documents". Same font, same size, different weight when visualising. If I alternate between the two, they always display different.

GNOME Tweak Tool does not respond well to changes in its fonts.

Workaround: Select a font you want, then close the app and reopen it.
