Re: Coloured character borders in kterm
Hello again! I went the Stable route. After a clean installation of Debian Stable, everything displayed fine... in KDE. But GTK applications had colored edges. After tweaking fontconfig and fontconfig-config with the same KDE settings GTK applications rendered nice fonts... except the smaller ones, who still display colored borders. Other applications like Telegram also display colored font borders in any font size... this is interesting because Telegram is a Qt program. In resume: I thought font rendering issues were something from the past but I was wrong. In 2023 it is still a serious issue affecting *every* Linux distribution. Anyway I will stay in Stable some time... My main applications are KDE based ones and a clean and crisp Konsole is a must for me. Thank you for all your tips.

Re: Coloured character borders in kterm
I have been testing some things trying to get the culprit package but I didn't find anything. The problem persists creating a new user and logging in with the new user. I also tried different fonts in Konsole and some of them are less affected than others but all of them have colored borders, making the terminal a text rainbow. I have seen some recent font related bugs in KDE's bugtracker but none of them seem to match my problem. Nobody else noticed this problem? Is it possible I have a missing package somewhere? I have installed task-kde-desktop but I'm not sure this guarantees all needed packages are installed. Thanks in advance
Re: Coloured character borders in kterm
Just for info, I managed to downgrade libfreetype6 and fontconfig to 2.11.1+dfsg-1 and the problem persists.

It is due to new settings in fontconfig-config, especially the symlinks 10-sub-pixel-rgb.conf and 10-yes-antialias.conf in /etc/fonts/conf.d. Try removing the first of these, and if you are still not satisfied with the result, the second as well. After that fonts should look the same as before, except that the default family is now Noto rather than DejaVu, see https://bugs.debian.org/1028643. Cheers, Sven

Re: Coloured character borders in kterm
Until january 13th it rendered perfect. Crisp and clean but after an apt upgrade the issue appeared. I tried to tweak the settings but no one brings back the rendering quality I had just three days ago. I always get rainbow-colored borders. The problem is I can't find the responsible package to try to downgrade it... or open a bug report against it. A web search for recent kde bugs or problems didn't show anything. It is quite unconfortable to work with a multicolored font everywhere but I don't know what to do now. Please if someone else noticed the problem please advice Thank you in advance
