Hmmm... I think I recalled why. Being just a few steps away from turning legally blind, I set the font size to 22, minimum font size 18. Oh... right. It doesn't matter anyways as long as I can read it.
hmm...looks like you are zooming the text through the "zoom text" option of your browser. i'm sorry to say that, but this will cause grapical "errors" on many graphically intense sites like the divinity 2 site is. please just set your zoom to "normal" or switch off the "only zoom text" setting and everything will look fine.
Ah well, no help for it. :P If I want to read the text comfortably, that is.

Thanks for all your help though. xD
