plain terminal output

As I move the mouse across the user interface in Steam client, or activate a
menu item or scrolling through the installed games' list in the library, text
in the user interface periodically disappears and reappears.
Also can be reproduced in the login window: as I begin typing in the input
fields, text disappears then reappears.

Disabling dwrite.dll or launching Steam with 'no-dwrite' parameter is a
workaround.
Reproduced in fullscreen and virtual desktop mode and with running Steam in
Windows XP and Windows 7 modes.

Reverting the following commit fixes the problem:
