Public bug reported:
After a recent update, many fonts are no longer rendering properly.
Only four characters will render for any text object.
The problem is widespread, and appears to affect gtk programs, but gtk
was not among the packages updated. As a control, I updated a laptop
that I hadn't used in about a week, and no problems occurred on that
computer.
The biggest difference between the two computers is the presence of a
Radeon graphics card in the affected machine (the laptop is using
Intel). And graphics drivers are among the updated packages on the
affected machine.
