The text in my PDFs is quite fuzzy and hard to read, and the thinner the text the worse it gets. This does not appear to be as much of a problem in other applications and I've uploaded a browser page (left) and a pdf (right) to show the difference. This makes me suspect it's something specific to the way PDFs are being displayed. I have checked using different PDF viewers and the problem is the same.
Font settings: Subpixel smoothing (LCDs)
Ubuntu Mate 16.10
Mate Desktop environment: 1.16.0
Any thoughts would be appreciated.
