[ft] Testing new LCD rendering mode
Hi, I tested new libXft LCD Filtering patch and I got some screenshots to show too :-) http://cekirdek.pardus.org.tr/~ismail/tmp/knode-old-lcd-rendering.png shows the rendering with old LCD rendering patch, its all good there. http://cekirdek.pardus.org.tr/~ismail/tmp/knode-new-lcd-filtering.png shows the rendering with new LCD filtering patch, notice that the blurriness of the font makes it look bad especially when its bold, also notice there are color fringes which looks like the case for vanilla libXft + enabling subpixel hinting. Test Environment: 8pt Tahoma, 96 dpi I downloaded libXft-2.1.7 and applied patch libXft-2.1.7-lcd-filter-2.patch . Thoughts? P.S: Example application used is KNode.

Did you enable the bytecode interpreter in FreeType for the second example ? It doesn't seem so.

Freetype library did not change between tests ( I am actually just installing old libXft testing, installing new libXft testing ), so I don't think thats the problem but I agree it just looks like that indeed.
