I had the same Problem. The monospace-font in konsole looked ugly after upgrade from 17.04. Same with freetype 2.8.1. Then I downgraded libfreetype to 2.6.3 as HorstBort mentioned, and konsole looks nice again. Here the description how I managed it:
1. add 'deb http://archive.ubuntu.com/ubuntu/ zesty main restricted universe multiverse' in '/etc/apt/sources.list' 2. create the file '/etc/apt/preferences' with the following contents: --- Package: libfreetype6:amd64 Pin: version 2.6.3* Pin-Priority: 1001 Package: * Pin: release v=17.04, l=Ubuntu Pin-Priority: -1 Package: libfreetype6:i386 Pin: version 2.6.3* Pin-Priority: 1001 Package: * Pin: release v=17.04, l=Ubuntu Pin-Priority: -1 --- 3. apt-get update -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to freetype in Ubuntu. https://bugs.launchpad.net/bugs/1722508 Title: Font hinting appears broken on 17.10 beta Status in freetype package in Ubuntu: Confirmed Status in freetype source package in Artful: Confirmed Bug description: It appears that font hinting in 17.10 (beta) doesn't work as expected. 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/ubuntu/+source/freetype/+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
