User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12
Build Identifier: Gecko/20101129 Firefox/4.0b8pre

This bug comes from https://bugzilla.mozilla.org/show_bug.cgi?id=611975
Now this bug is fixed in non-HW accelerated Gecko, but with HW acceleration it is still broken.

Reproducible: Always

Steps to Reproduce:
1. Open testcase with D2D accelerated FFX on Windows7/Vista
2. Save a screenshot
3. Disable HW acceleration
4. Open the same testcase
5. Compare screenshot and current rendering
Actual Results:  
D2D accelerated gradient on stroke is too bright, almost not noticeable => it differs from non HW accelerated one much

Expected Results:  
Both renderings should be the same, are nearly very the same, but they're not.
