Hi Phil and all, I was working on backporting this to 11:
https://bugs.openjdk.java.net/browse/JDK-8214481 When I realised this is actually a regression in that it makes rendering on OpenJDK worse in some cases. I've been testing with 8, 11, 13 and 15 and 11 patched and comparing those the fonts rendering becomes blurry when fractional rendering is used: http://cr.openjdk.java.net/~neugens/JDK-8214481/1.png http://cr.openjdk.java.net/~neugens/JDK-8214481/2.png A you can see the rendering in all cases is cleaner, the font is both blurry and thicker with the patched version. This is not the case, however, with the font provided by original bug report: http://cr.openjdk.java.net/~neugens/JDK-8214481/3.png In this case indeed the rendering is better at lower sizes (but not at higher, where the same blurring is apparent). I filed a new bug to track this with a reproducer that is derived from all the various test cases floating around 8214481: https://bugs.openjdk.java.net/browse/JDK-8242285 Cheers, Mario -- Mario Torre Associate Manager, Software Engineering Red Hat GmbH <https://www.redhat.com> 9704 A60C B4BE A8B8 0F30 9205 5D7E 4952 3F65 7898
