If I understand correctly, RGBA antialiasing *is* patented technology we are taking about. Hinting patents already expired, so grayscale+hinting can be used freely everywhere.
I had filed a prior bug report about the font issue: https://bugzilla.suse.com/show_bug.cgi?id=904238 They gave this link about the possible patent issues: http://david.freetype.org/cleartype-patents.html I know absolutely nothing about the underlying font rendering technology, and even less about patent law, but my understanding was that RGBA antialiasing is not the same as sub-pixel rendering, and that only the sub-pixel rendering is patent-encumbered. I very well could be wrong, though. I do know that on any distro, including openSUSE, for years it has been possible to enable RGBA antialiasing in the Gnome or KDE font settings, and it does improve font rendering considerably. But on openSUSE that configuration still doesn't look as good as it does out of the box on Arch or Ubuntu.
I noted in the above bug report that using *just* the Infinality fontconfig (not the libraries that actually implement the patent-encumbered process) with the standard openSUSE font rendering libraries does considerably improve things on openSUSE. As mentioned earlier in this thread, maybe something similar to this is in the process of being implemented now for openSUSE.
Can we expect an update for openSUSE 13.2 with the mentioned font rendering improvements? Or will it only get pushed out to Tumbleweed and the next fixed released after 13.2? As I mentioned earlier, the folks in Factory are working on patching stuff with the Infinality tech.
