This is from the value you set for the "rgba" parameter in fontconfig. When you set "rgb" there you're saying that you have sub-pixels in the order of red, then green, then blue horizontally. If you happened to have a reversed display devide, then you would set "bgr" there instead. And if you have a device rotated so that the sub-pixels are vertical rather than horizontal, then you can use "vrgb" or "vbgr". > The thing that still confuses me is that both Konqueror and Iceweasel have > colored edges in their window title font in Yes. I noticed that this last time too. I don't know where that's coming from, (perhaps a bug in the window manager in that *it* is not respecting your font configuration settings). > Okay.

No idea.

It's simply a matter of coming up with configuration options that make sense enough for me to be willing to accept them with my "upstream cairo" hat on. :-) > I completly understand that.

Could you look into that and see what they come up with for configuration, if anything? -Carl -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
