[Pkg-urxvt-maintainers] Bug#743641: rxvt-unicode: color fringes appearing when using sub-pixel antialiased hinted fonts

[Benjamin Cama]

Package: rxvt-unicode
Version: 9.15-2
Severity: normal

Hi,

On my system, I used to have urxvt with a special font rendering of
mine which worked correctly with squeeze: I use DejaVu sans at 11pt,
with hintstyle=hintfull and lcdfilter=lcdlegacy, using RVB sub-pixel
rendering. This worked nicely, and seems to continue to work correctly
on wheezy with gnome-terminal and xfce4-terminal, but not with urxvt;
the the attached screenshot as an example.

What I see are sligthly exagerated color fringe, that are typically
associated with sub-pixel rendering, but which are here very noticable.
It looks like blending is made incorrectly. This is a bit annoying to
the eye. You can see it very well with "w" for example.

BTW, I see that colord is running, but I don't know if this has some
influence; I didn't calibrate my screens at all with it. I'm also
running XFCE4 as desktop environment, if this is relevant; but I also
whitnessed it under Gnome at home.

I would be interested if some other people saw that too.

Regards,
benjamin
