It appears that font hinting in 17.10 (beta) doesn't work as expected. The issue is easy to miss if you have antialiasing enabled system-wise. However, if you install "gnome-tweak-tool" and disable antialiasing there, the problem becomes obvious.
* When comparing the pictures make sure you "Open image in new tab" and see them without browser zoom, otherwise the problem may no be obvious.
I suspect that this issue is caused by a bug in some base font rendering package that Ubuntu uses. A couple of months ago a similar issue was reported (and promptly fixed) in Chromium after they had changed something in FreeType rendering (https://bugs.chromium.org/p/chromium/issues/detail?id=748997).
