Running Opera Developer Version - 48.0.2679.0 (PGO) on my Windows 10 Pro Laptop. Laptop has 4K screen, so that might also be the cause of issue (though wikia pages work fine on other browsers).

Here's a screenshot of the the overly zoomed page - http://imgur.com/a/UJ4pU
This is at 100% zoom.

Used to work fine before the recent update.

Is this a problem faced by everyone? If not then what should I do to change it... Because navigating history is now a pain...
