I just installed the new KDE Neon Bionic version as a VM. The Trick doesn't work there. The freetype-version is 2.8.1-2ubuntu2 like on the Kubuntu Host. Maybe the /etc/environment is ignored there.

Hi Martin, Thanks for the tip! Defining the FREETYPE_PROPERTIES as you suggested in /etc/environment did indeed disable hinting and renders the same crisper fonts as was in earlier versions of Ubuntu. Personally, I still prefer to disable hinting in the source code but your suggestion works just as well. Thanks again!

> Its not so much that the font rendering is better or worse but that it is different than before Gordon, thanks for your reply. I think your issue is different than the Qt issue mentioned by many of the commenters here. I help maintain Ubuntu's font packages, but I just started with that and I wasn't involved in the freetype 2.7/2.8 upgrade nor am I familiar with how Ubuntu's font rendering used to work. I encourage you to start a Desktop topic at https://community.ubuntu.com/ for your suggestion. If you could provide before and after screenshots, that would be helpful. We might want to keep a more upstream default font rendering. I don't know, but I am hopeful that your post will help us figure out what to do. By the way, I expect we'll be upgrading to freetype 2.8.1 for Ubuntu 18.04 LTS, but I am waiting for the next Electron release first.

[Bug 1722508] Re: Font hinting appears broken on 17.10 beta
Hello jbicha, I am not running Kubuntu but I am running KDE Plasma 5 and Qt apps on several OpenSUSE installations. On my Ubuntu installation I am running Gnome Shell. As an FYI, I maintain a freetype2 repository with subpixel rendering enabled for OpenSUSE Leap and Tumbleweed. Like most of the other Linux desktop OS versions, OpenSUSE does NOT enable subpixel rendering with the FT_CONFIG_OPTION_SUBPIXEL_RENDERING variable and I provide that option with my repo. In one of my repos I use the Ubuntu freetype2 diff file for implementing the subpixel rendering patches. Several months ago, I noticed that the font rendering changed when I upgraded my font repositories to freetype-2.7.1 and the difference in the rendering was caused by the introduction of the TT_CONFIG_OPTION_SUBPIXEL_HINTING parameter in ftoptions.h. Its not so much that the font rendering is better or worse but that it is different than before with freetype-2.6.X. In any event, at that time, I discovered that the font rendering would be made exactly the same as before by not defining TT_CONFIG_OPTION_SUBPIXEL_HINTING in freetype2 versions 2.7 and later. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1722508 Title: Font hinting appears broken on 17.10 beta To manage notifications about this bug go to: https://bugs.launchpad.net/qt/+bug/1722508/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs

[Bug 1722508] Re: Font hinting appears broken on 17.10 beta
One of the primary differences in freetype-2.8 and prior Ubuntu versions of freetype is the introduction of TT_CONFIG_OPTION_SUBPIXEL_HINTING in /include/freetype/config/ftoption.h in freetype-2.7.X and later. The default value is: #define TT_CONFIG_OPTION_SUBPIXEL_HINTING 2 This needs to be undefined (uncommented) in order for freetype-2.7 and 2.8 to render fonts identically to prior versions of Ubuntu freetype (freetype-2.6.X and earlier). The diff file (freetype_2.8-0.2ubuntu2.diff.gz) at https://launchpad.net/ubuntu/+source/freetype/2.8-0.2ubuntu2 enables FT_CONFIG_OPTION_SUBPIXEL_RENDERING in /include/freetype/config/ftoption.h with: #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING This properly enables subpixel rendering to render fonts identical to MS cleartype, however, if TT_CONFIG_OPTION_SUBPIXEL_HINTING is also set then the fonts are rendered differently than before. So, this problem is fixed simply by undefining TT_CONFIG_OPTION_SUBPIXEL_HINTING. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1722508 Title: Font hinting appears broken on 17.10 beta To manage notifications about this bug go to: https://bugs.launchpad.net/qt/+bug/1722508/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
