Flex 4.5/FP10.2 web app: Font rendering problem

Question

Heya,
Upped a web app from Flex 4.0/4.1 to Flex 4.5 & fonts started to render really badly (blurry & 'stronger').
They are embedded as CFF, no errors or warnings gives. Also upgraded to Flash Player 10.2, which apparently has 'enhanched' font rendering.
Haven't set applicationDPI on the s:Application tag, so DPI management should be disabled according to the docs.
(See http://help.adobe.com/en_US/flex/mobileapps/WS19f279b149e7481c682e5a9412cf5976c17-8000.htm l)
It's straight up @font-face embeds in a CSS file, nothing odd or wrong there.
Is the case that this is how it's supposed to look now? In that case, how do I revert back to sane rendering?
Do I need to configure 4.5 somehow to get it to do fonts right?

Also tested Franklin Gothic, same deal. Tested on Mac (10.2) & PC (10.2 & 10.3). Flex 4.5 for both platforms.
fonts.css:
@font-face
src: url("fonts/arial.ttf");
font-family: Arial;
font-weight: normal;
embedAsCFF: true;
FontTest.mxml:
