I've been having this issue since 10.5 but haven't seen anyone else reporting this, so i thought i'd ask if anyone else's having the same or it's just me.

The problem is easy to spot: Firefox, Thunderbid and some other programs look a lot darker than they should. I've triend with and without new Direct2D / XAA.

Example of what i mean:

As you can see, images in Firefox are a lot darker than in Chromium. And it's not limited to pages, Firefox icons and backgrounds are also darker.
