Created attachment 262101 [details] Shows irregular kerning on youtube settings page I'm using the GNOME browser (formerly known as epiphany) with webkit2gtk 2.10.0 on Debian Linux on a Macbook 13" Retina. I've applied the patch from bug #141782, but now on many pages the font kerning looks wrong, with irregular spacing between characters. I found bug #109955, but I think this is a different issue because of the different OS etc, and the custom CSS suggested there made no difference. I suspect this is another problem with accelerated rendering. Could it be anything to do with bug #146194?

Created attachment 274594 [details] Another example of terrible font spacing in GNOME "Web" This bug is still a problem in Debian with GNOME "Web" using libwebkit2gtk-4.0-37 version 2.10.8-1. You can see how ugly it is. Please can somebody look into it.

Strangely DevHelp doesn't appear to have this problem, despite using the same webkit-gtk package. But I think it's probably due to them using different options, and one of those options is bugged in webkit, rather than the bug being something caused specifically by Web.

Unless I'm mistaken, I don't think either of those websites are using the complex font layout path, so there would not be any kerning at all. Hence I guess this is bug #167557. Please complain if you disagree. *** This bug has been marked as a duplicate of bug 167557 ***
