Is your Issue reproducible when you disable the Hardware Acceleration and restart Firefox?

If yes, please post the Content of the Graphics Section you can get via "about:support" after you re-enabled Hardware Acceleration.

Sounds like some existing bugs we have on color fringing with dwrite due to the subpixel aliasing....

Comment 4

The Issue is not reproducible without hardware acceleration on firefox

anyway here's the graphic content from "about:support"
