No anti alias in gtk applications [solved]

mingfal · 2006-07-18 07:24:40

There's no problem with other applications and there was no problem with my gtk applications.
But the anti aliased fonts in the gtk apps disappeared yesterday and I hadn't edited any configuragion files about fonts.

So what is wrong?

And there's another problem in the gtk applications.

Sometimes some characters disappear and if I select them,they appear again.

Try GTK_XFT=1 in your .xinitrc

mingfal · 2006-07-18 14:58:23

Thanks a lot,but that doesn't work.
The gtk apps do use xft fonts,but without anti aliasing.

cairo sometimes ignores settings of antialias in fonts.conf and local.conf.

It is Cairo. It's being worked on. Revert back to the previous version and your fonts will be fine.

Look in ~/.fonts.conf and disable all settings that set an exclude range for anti-aliasing on font sizes. Also disable those things in /etc/fonts/* if you made changes to that.

Cairo has a bug and thinks all fonts are that size, so it disables AA completely. The bug with only the first word appearing was introduced with cairo 1.0.4, which occurs only with unscalable fonts. It looks like cairo 1.2.0 makes unscalable bitmaps from fonts when disabling anti-aliasing, which triggers the bug already present in 1.0.4.

Two critical bugs for these are opened at freedesktop.org, there's not much known about fixes or causes for this, they're still investigating. The problem does not appear when using EXA, so it wasn't noticed on time by the developers, as they use EXA.

Thanks to all you guys.The problem solved after I deleted the directory ~/.kde.
I wonder what kde setting made the gtk apps lose anti aliased fonts.

Perhaps you had gtk-qt-engine installed and some special font settings there?

mingfal · 2006-07-26 17:53:41

I'm afraid not.
I installed gtk-qt-engine when I was using debian a long time ago and that sucks.Since then I've never had gtk-qt-engine again.

IIRC the latest version has had some performance improvements... Not using it now though, so I don't really know how well it works.

Has this bug been fixed by the Cairo developers? Also, I tried using EXA (putting Option "AccelMethod" "exa" in my card's device section in xorg.conf, I have a Radeon 9700 card using the oss driver), but that didn't resolve the issue either. Only programs using libxft respect the antialiasing settings in the .fonts.conf file

I'm pretty sure it's fixed in 1.2.x. What version are you using?

hjorthboggild · 2006-10-03 09:53:25

I'm using the one in current, 1.2.4 I believe it is

Arch Linux
