--- Comment #4 from Mike Kaganski <[email protected]> ---
This is not a regression at all.
Additionally, the text is not black nor grey ;P

PowerPoint defines the text in question to use "Dark Green, Text 2" color,
solid fill, 50% transparency (visible in "Format Shape" panel under Text
Options->Text Fill).

Before the commit identified in comment 3, Impress ignored the transparency
completely, rendering the text much darker than in PowerPoint (it just used the
color #0C322C, which is the value of the "Dark Green").

The mentioned commit made Impress *correctly* treat the transparency value,
*resulting in correct match* of the PowerPoint resulting color.

The problem here is how anti-aliasing is handled together with transparency.
There is some (pre-existing) bug here, and since this text is rather small,
giving around 1-2 pixel wide strokes at normal resolution, AA gives a huge
distortion here. You may see a very different picture at e.g. 400% zoom.
