Bug#956513: Regression: font spacing of monospace fonts broken

[Attila Kinali]

Package: libgtk-3-0
Version: 3.24.14-1
Severity: normal

Hi,

The last update of gtk seems to have broken rendering of monospace fonts.
The spacing of the letters got reduced to almost nothing. Attached
are two pictures, taken from sylpheed 3.7.0 using DejaVu Sans Mono Book 8pt,
only difference being different versions of gtk.
