Bug Description

After replacing Xubuntu 14.04 with 16.04 (a fresh install from the ISO) I have found that the system's monospace font is being incorrectly rendered in some applications. It seems that too much space is being placed between the characters, perhaps because the typeface hinting is being ignored?

I have attached an image that shows DejaVu Sans Mono rendered at 10pt in Pluma 1.12.2, Xfce Terminal 0.6.3 and Code::Blocks 13.12. Only the Xfce terminal uses the correct kerning, the others space the characters too far apart.

This is making development work extremely difficult because lines of code are now displayed much wider than they were before.

It actually seems that the example I initially provided is wrong. The XFCE terminal is actually rendering the font at 9pt, when I switch it up to 10pt it looks as wrong as the other two.

As far as I can tell then, the problem actually seems to be that 10pt is being rendered at the same height as 9pt with the only change being an increase in width.

Turns out this is actually a bug in freetype. I have added to an existing bug report on their tracker.
