[Message part 1 (text/plain, inline)]

Hi,

In the trunk of Emacs 24.3, I cannot seem to get anti-aliased font rendering. I've tried customizing, etc. but nothing seems to work. Is this a known problem and if so, is there a fix?

I've attached a screenshot of 24.3 and 24.3 side by side to illustrate what I am talking about.

Thanks
Sudhir

I assume you mean something else than "24.3 and 24.3"?  There is no "trunk of 24.3", it is just the trunk or the emacs-24 branch or a released version.  Not sure what versions you mean here.

Anyway, both your versions are antialiased as is plainly seen if you zoom in on a character so you see the individual pixels.  I suspect one of them is not LCD-smoothed though.  See bug 11484 (http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11484).

If another workaround for that bug can be found, smoothing will be turned back on.

Closing, as this is not a bug.

Thanks,

	Jan D.

Sorry for my poor reporting - it was trunk vs. 24.2

You're correct - I should have said LCD smoothing and not anti-aliasing. I read the description of 11484 and now understand why smoothing was turned off. However, now Emacs is quite unpleasant to the eyes and quite unusable on a Macbook IMHO. Perhaps the cure is worse than the disease? 

Thanks

Hello.

The emacs-24 branch (and soon the trunk) has smoothing on again.
