Description temporary987 2014-06-16 13:44:45 UTC 
As you can see on the screenshot, in Muon package list, KRunner output window and in Kickstarter menu fonts are a bit blured, while in other programs they look fine. I can get this result globally if I disable subpixel hinting (rgb) in fonts settings. So, some KDE applications do not respect my Subpixel Hinting settings. They are also set in /etc/fonts/conf.d/.

Reproducible: Always

Steps to Reproduce:
1. Enable Subpixel Hinting (rgb) in fonts configuration
2. Open Kickstarter menu, Muon or type a query in Krunner (Alt+F2)
3. Look at the fonts
Actual Results:  
Fonts look like in other applications and they use Subpixel Hinting

Expected Results:  
They seem to ignore Subpixel Hinting settings.

I also noticed, that in some distros (for example, Gentoo) with Xfce, KDE or pure WM GTK-applications ignore subpixel hinting. Probably, there are some relations?

Qt is no longer nokia's, as I know.
Here https://bugreports.qt-project.org/browse/QTBUG-22334 this bug doesn't seem to be resolved. Which version of Qt should I try?
Comment 3 Christoph Feck 2014-06-17 19:43:51 UTC 
I think the change was introduced in Qt 4.8, so you could try Qt 4.7.

The issue also appears in the K menu and desktop settings dialog

Here are screenshots
