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.

The issue is easy to miss if you have antialiasing enabled system- wise. However, if you install "gnome-tweak-tool" and disable antialiasing there, the problem becomes obvious. Here is how it looks on 17.10 beta: https://postimg.org/image/3auqsbkqtn/ And here is how it looks on my 16.04 machine (and this is pretty much how it's supposed to look): https://postimg.org/image/85n5ss3l4b/ * When comparing the pictures make sure you "Open image in new tab" and see them without browser zoom, otherwise the problem may no be obvious. I suspect that this issue is caused by a bug in some base font rendering package that Ubuntu uses (edit: the problem is probably caused by FreeType 2.8.0, see my comments below). A couple of months ago a similar issue was reported (and promptly fixed) in Chromium after they had changed something in FreeType rendering (https://bugs.chromium.org/p/chromium/issues/detail?id=748997). lsb_release -rd Description: Ubuntu Artful Aardvark (development branch) Release: 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/qt/+bug/1722508/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
