Look at the attached images.
Pairs of image, and its expected copy (from previous buids).

I see on b123, that both in d3d and sw renderings I see strange way of rendering.
Look on "S" letter -the first one in "some more text" phrase with strange dots in the bottom.

Looks bad.

I see such rendering everywhere.

Look at strange rendering of ToggleButtonsTest-setEllipsisString.png with "g" letter.
