This is how it displays:
it doesn't look right, somehow. But I don't know where to look. Changing the default font in Th settings does nothing.
The desktop apparently uses "Sans", whatever that is, but the preview there doesn't match what I see in Th. either. I have changed there to "Luxi Sans", to see if Th changes. Not that I can see :-?
do
$ fc-match sans
to find out which font it is. I can't tell from that image what bothers you. Those fonts are all much too small here. Has it always been like that, or just changed after updating?
