The Subpixel Rendering support was removed from FreeType2 in openSUSE due to the patents reason. And the documentation of Leap mentions that these patents would expire at the end of 2019.

I am recently interested in font configuration, so I would like to confirm if Subpixel Rendering is avaliable now in Tumbleweed. Since it's 2020, those patents should have been expired, but I am not sure if openSUSE has compiled them in.

I am not seeing anything about it in the revision log of package libfreetype6, and since the notification of patents still exist in the documentation of Leap 15.2 (which released several months ago), I wonder if there are still certain restrictions.

There does has an option of Subpixel Rendering in yast2-font, but I am not sure if it's the full version of Subpixel Rendering...
