[Bug 1311854] [NEW] Fonts corrupted when scrollbars appear

[Hugh Malard]

Public bug reported:

Hello,

I have noticed that the fonts of certain programs become corrupted when
scroll bars appear. They are not corrupted when there are no scroll
bars. This took a while to understand and does not affect all
applications. I have noticed this behavior in Gedit and Synaptic, so I
think it is not a problem related to a specific application. I have
filed this bug under fontconfig, but I am not actually sure the cause of
it. This is also a new problem with Ubuntu 14.04. I upgraded from 13.10
and that version did not have this problem.

To illustrate this font corruption I have attached a screenshot of
Gedit. As soon as the scrollbars appear the text becomes blurry.

** Affects: fontconfig (Ubuntu)
     Importance: Undecided
