[Bug 1999078] New: Hinting broken for Bitstream Vera/DejaVu in Epiphany

https://bugzilla.redhat.com/show_bug.cgi?id=1999078 Bug ID: 1999078 Summary: Hinting broken for Bitstream Vera/DejaVu in Epiphany Product: Fedora Version: 34 Status: NEW Component: freetype Assignee: mkasik(a)redhat.com Reporter: ossman(a)cendio.se QA Contact: extras-qa(a)fedoraproject.org CC: ajax(a)redhat.com, caillon+fedoraproject(a)gmail.com, fonts-bugs(a)lists.fedoraproject.org, gnome-sig(a)lists.fedoraproject.org, kevin(a)tigcc.ticalc.org, mark(a)net-c.com, mclasen(a)redhat.com, mkasik(a)redhat.com, rhughes(a)redhat.com, rstrode(a)redhat.com, sandmann(a)redhat.com Target Milestone: --- Classification: Fedora Created attachment 1819062 --> https://bugzilla.redhat.com/attachment.cgi?id=1819062&action=edit Screenshot with varying sub pixel placement Description of problem: After upgrading from Fedora 33 to Fedora 34, there is some extremely odd hinting bug in Epiphany. The same glyph appears with different amount of hinting in the same line of text, causing a very odd and blurry appearance. Version-Release number of selected component (if applicable): freetype-2.10.4-3.fc34.x86_64 bitstream-vera-sans-fonts-1.10-41.fc33.noarch dejavu-sans-fonts-2.37-16.fc34.noarch epiphany-40.3-1.fc34.x86_64 webkit2gtk3-2.32.3-1.fc34.x86_64 pango-1.48.9-2.fc34.x86_64 How reproducible: 100% Steps to Reproduce: 1. Configure Epiphany to use Bitstream Vera or DejaVu Sans Book 2. Configure full hinting Actual results: Fully hinted, consistent glyphs. Expected results: Some glyphs are fully hinted, some look like they've been offset by a fraction of a pixel. (See screenshot) Additional info: So far I'm only seeing this in Epiphany. I still filed this for freetype since as far as I know it is freetype that does all glyph layout, hinting and sub-pixel stuff. Feel free to move as appropriate. So it seems odd that a bug in Epiphany can screw this up. -- You are receiving this mail because: You are on the CC list for the bug.
