Steps to reproduce:

Just open winehq.org with firefox under linux. I use Neon distribution based on ubuntu. By default RGB rendering isn't enabled, but it's easy to switch inside options. Usually pages open fine, with RGB smoothing enabled but some, like this and facebook (only some parts of page is affected) use grayscale subpixel rendering. Under Windows all works fine.


Actual results:

Greyscale subpixel rendering is used instead of RGB.


Expected results:

Fonts should be smoothed using RGB subpixel rendering.
