Created attachment 882473 [details] testcase with the problematic font charakteristics Wikipedia recently switched to a predefined CSS font stack for body font so even Windows users will be served with Liberation Sans if installed (e.g. because it is distributed with Libre Office). This made apparent inferior hinting of Liberation Sans with bold weight when rendered at the specific size of 0.875em (the font size used in MediaWiki's vector skin). Most notable "e"s have a very thick lower curve while the upper curve is much too thin. This also applies for variants like "è é ê ë". Funnily not for "œ æ" though which is rendered differently. Also notable is e.g. "s" which has thick upper/lower curves but is thin in the middle. A testcase with the described font characteristics set is attached. The screenshot shows the rendering in Firefox. The screenshot was created with Firefox 28.0 on Windows 7. The installed version of the Liberation fonts is 2.00.1

Is anything being done about this issue? Is annoying when this font is used in documents and on the Web on Fedora 21. I've noticed there's a version 2. Why isn't it being released?
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Any work on this bug? Still present in Fedora 22 :( Could you please change the 'version' if possible? Packages present in Fedora 22: liberation-mono-fonts-1.07.4-4.fc22.noarch liberation-sans-fonts-1.07.4-4.fc22.noarch liberation-narrow-fonts-1.07.4-4.fc22.noarch liberation-serif-fonts-1.07.4-4.fc22.noarch liberation-fonts-common-1.07.4-4.fc22.noarch
Unfortunately not any progress yet. Is there any chance for patch? We can work on evaluating same. Even if not, i will see if can resolve issues during F22 development cycle.

I honestly don't know how to write a patch for these things :/ Can contribute my time if someone can guide me through if possible. Why not jump onto the next version 2.00? https://fedorahosted.org/liberation-fonts/
1. Hinting in Liberation one looks like Manually done. That is why its tricky to update. I will find some guides and update you. 2. Hinting in Liberation 2.00 is done with some automated tools and does not give as sharp output as Liberation1. We tried this switch in particular Fedora version but lots of people complained so decided to switch back. Conclusion we came up with Liberation 1 and 2 are not compatible for Hinting rules.
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
