Okular: 1.10.3 but the poor font rendering was also happening before

Here are the font rendering (sorry but the images are too wide, here are the imgur links):

See heading: "CHAPTER 2: THE 6 THINGS EVERY MARKETER MUSH KNOW"

mupdf: https://i.imgur.com/PuhXrL4.png
MasterPDF: https://i.imgur.com/m1LC0F7.png

The problem is not with the font itself since neither mupdf nor masterpdf have problem with the rendering.

Is there some setting that I could change?

Thanks
