https://bugzilla.novell.com/show_bug.cgi?id=245540 Summary: Anti-aliased fonts in KDE are problemactic Product: openSUSE 10.2 Version: Final Platform: i586 OS/Version: Other Status: NEW Severity: Minor Priority: P5 - None Component: KDE AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: romain.pelissier@gmail.com QAContact: qa@suse.de In OpenSuse 10.2 when font anti-aliasing is activated in configure Desktop / appearance and Themes / Fonts and the hinting style is set to Full, then fonts on the desktop appear buggy and other texts that are displayed in KDe does not appear to be anti aliased at all. but if hinting style is set to Medium then the desktop fonts are correctly anti-aliased. Note that on another computer it was also happened to me when I changed the configuration of the screen (monitor type) in sax2. This time, I have not changed the sax2 config since the monitor is correctly detected. Is there a way to have the hintitng option set to hight without issue? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

As you can see, when set to hight there is no anti alias at all for the fonts. When set to medium, it is much better some fonts have like a kind of shadow. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

There is anti-aliasing. You can use "xmag" to magnify text on your screen and convince you that there is anti-aliasing. Roman Pelissier> When set to medium, it is much better some fonts have Roman Pelissier> like a kind of shadow. I don't think it is better. It is much blurrier, there is far too much gray. With hintstyle=hintfull, you get much sharper glyphs. These glyphs are rendered with the byte code interpreter which gives very crisp and sharp glyphs with full hinting when fonts which have good byte code are used (which is the case in your screen shot). If you want blurrier fonts you can switch off the byte code interpreter and use the autohinter instead. There is no GUI to do that, you have to edit your ~/.fonts.conf file. Create such a file if it doesn't exist yet. Example contents of a ~/.fonts.conf file switching on the autohinter: <?xml version="1.0"?> <fontconfig> <match target="font" > <edit mode="assign" name="rgba" > <const>rgb</const> </edit> </match> <match target="font" > <edit mode="assign" name="hinting" > <bool>true</bool> </edit> </match> <match target="font" > <edit mode="assign" name="autohint" > <bool>true</bool> </edit> </match> <match target="font" > <edit mode="assign" name="hintstyle" > <const>hintfull</const> </edit> </match> <match target="font" > <edit mode="assign" name="antialias" > <bool>true</bool> </edit> </match> </fontconfig> I like autohint=false much better though. Not using the byte code interpreter for fonts with good byte code results in much blurrier glyphs. It throws away all the effort the the authors have invested to make the glyphs render sharply. Closing as WORKSFORME because this is just a matter of taste and I think the results with the byte code interpreter (your screen shot in comment #2) are far superior. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I will give you as attachment another screenshot with your fix and also my actual fonts.conf file. As you can see with the new screenshot, there are some texts under some icons that are buggy. But if I reapply the setting (changing the anti alias option and revert back) then all is good again. Also, if I log off and login again, the font are correct this time. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

The problem with the shadows doesn't look like a font rendering problem at all, i.e. it is somebody elses problem, not my problem.
