screenshot of konqueror with overlapping chars
I cannot reproduce this (on fedora 16, x86_64, kde-4.7.95) It probably depends on the default font, which is here "Nimbus Sans L". Also with "Liberation Sans" and other fonts I see the bug. Minimum Fontsize = 10 Any other settings which might influence this ? Maybe this is related to bug 290485 ? still can't reproduce this with any combination of --graphicssystem (native or raster) or switching to Liberation Sans (was using DejaVu previously) Ok, I found out. It has to do with the MediumFontSize configuration. When this is 10 or 11 when I have the MinimumFontSize=10 then you'll see the problem. When I have MediumFontSize=12 then you don't see the problem. But all this together only when you have the following inside ~/.fonts.conf <?xml version='1.0'?> <!DOCTYPE fontconfig SYSTEM 'fonts.dtd'> <fontconfig> <match target="font"> <edit mode="assign" name="hintstyle"> <const>hintslight</const> </edit> </match> <dir>~/.fonts</dir> </fontconfig> I don't know why I have that file at all. I sure did not create it manually, but from the timestamp I see that it was last modified in June last year, so long before my upgrade to 4.8rc1 I found out that this file (.fonts.conf) is created by the KDE kcm for the fonts in the Anti-Aliasing configuration and when I set hinting style to slight. In the meantime I have upgraded my installation to openSuse 12.1 but I'm now back on KDE 4.7.2 but still with Qt4.8.0 - and the problem is still there. So this seems to be a regression with Qt (or it's a bug in khtml which shows just now) Created attachment 69970 [details]

hintslight vs. hintfull when using Konqueror (with KHTML) or Akregator
I can confirm this when using hintslight with Konqueror (with KHTML-engine) or Kontact (Akregator).
When I change the fontsettings (in /etc/fonts/conf.d) to hintfull the fontspacing looks correct.
Konqueror with Webkit-engine also have correct fontspacing (no matter which hintstyle is used).
Graphicssystem (native or raster) have no influence.
The bug is still there after upgrading to KDE-4.8.2 and Qt-4.8.1. The first time I've seen this bug is with KDE-4.8.1 or maybe KDE-4.8.0. More information about the attachment in comment #9: Bug is visible on the startup screen of Akregator when: - Setting in /etc/fonts/conf.d the hintstyle to hintslight; - Setting in Akregator the Standard font to Arial, Candara or Verdana; - Setting in Akregator the Medium font size to 11 Using hintfull will make the bug disappear, using an other font or fontsize will make the bug less visible. More information that may be important: - Output of 'xdpyinfo | grep dots' is '96x96 dots per inch' - Graphicssystem set to native or raster makes no difference; - Different versions of freetype2 makes no difference Dear user, KHTML (and KJS) was a long time more or less unmaintained and got removed in KF6. Please migrate to use a QWebEngine based HTML component. We will do no further fixes or improvements to the KF5 branches of these components beside important security fixes. For security issues, please see: https://kde.org/info/security/ Sorry that we did not fix this issue during the life-time of KHTML. Greetings Christoph Cullmann |
