Bug Description

Upon upgrading from feisty to gutsy on my main machine, I noticed that fonts are generally blurrier, in both GNOME and KDE applications, with my current settings, which are subpixel antialiasing, with full hinting. I took a screenshot from a second machine that I had installed a fresh copy of gutsy tribe 5 on, which is up to date as of yesterday, and it displays fonts in exactly the same way, so this shouldn't be hard to reproduce. I will attach a comparison image to illustrate what I'm referring to as a bug here.

This image shows fonts as displayed in the System Monitor Preferences applet window. In all three cases, subpixel antialiasing is enabled with full hinting.

The topmost slice is from my main machine before upgrading to 7.10.
The middle slice is the same machine, after updating to 7.10 - I've tried rebooting, switching my font settings around, deleting ~/.fonts.cf, etc.
The bottom slice is from a second machine with a fresh install of 7.10 Tribe 5, updated to the latest packages in the archive as of yesterday, October 15th.

I think I have the same issue, Gutsy's fonts look more blurry than Feisty's. Changing Smoothing from 'Subpixel (LCDs)' to 'Grayscale' in the Font Rendering Details makes it better though.

I can't agree with that. For me Gutsy-style hinting is better than the one in previous versions. It seems to be a matter of taste.

Indeed, but in Feisty you could turn down hinting to accommodate your
tastes, whereas there is no alternative for people who want full
hinting in gutsy.

I have the same issue. The subpixel smoothing is blurred on Gutsy, it was perfect on Feisty.

I'm marking this as confirmed, since there is agreement from another user that the bug exists.

I created the file /etc/fonts/conf.d/lcdfilder-legacy.conf with the content suggested by towolf, but nothing happened. Yes, I restarted fontconfig, the X server, then the whole system, but without success.
Is there a sure way to get the "legacy" behavior?

I also have created ~/.fonts.cf, and nothing seems to have changed.

I turned off hinting but i still get blurry ness in the console window only when i'm installing an application or updates and watching it, everything else seems fine, by the way i'm using a CRT with subpixel on with hinting off tho makes fonts look better on my 17f3 monitor from eview. :) abeit with that SOOOO minor drawback at times..
