How to solve weird font spacing in window title

[Mr_Bumpy]

To anybody who is experiencing bad font spacing in window titles, there is a solution. Here is the bug report, and here are the instructions to resolve this issue:

The workaround is to switch Kwin to use the raster graphics system. First, test the raster graphics system using the following command:

kwin --replace --graphicssystem=raster &

If this solves the issue for you, you can make the setting permanent by creating the following script as /usr/local/bin/kwin-raster and making it executable:

#!/bin/bash
kwin --graphicssystem=raster

Then, add the following to /etc/profile:

export KDEWM="kwin-raster"

I hope this helps someone

Neat find! Many months ago this idea surfaced for the Qt graphics system; you can now install kde-config-qt-graphicssystem to obtain a Systems Settings control module to set which graphics system to use for Qt. Nice to see the same idea applied to KWin.
