Improve fonts rendering on linux. Fonts are too crisp

I have used opera for more than 5 years, and really like this browser. Now I'm using Linux and need to say the new beta version for linux is also great... Opera provides the new level of system integration with 10.53, now browser uses system theme. Also 10.53 is faster and regardless it is still in beta, more stable, especially with Flash content...

But what bothers my is fonts rendering. What bothers me more, it is no longer in known issues, what means no more improving in this direction. Am I right?

But as a linux user I've noticed great degradation in fonts rendering even with the latest snapshot comparing to 10.10 and other linux browsers.

Here are screenshots for Opera 10.53, Opera 10.10 and Chromium

Fonts in Opera 10.53 are too sharp and crisp (I don't know which word is appropriate, as I don't speak English natively).

I want to know, if some work on fonts rendering is going to be done?
And I'm begging Opera developers to use system font rendering or similar one as it was done for system theme.

Best regards.

As you can see, fonts in Chrome are less hinted (I use medium hinting). That's why fonts look more blurry and they are easier and softer for eyes.

But it seems like Opera 10.53 uses full hinting. Fonts' shapes are more impacted by a pixel grid. It is closer to Windows' cleartype technology. Fonts are lighter, sharper and more contrasting. That's why, they cause pain in eyes without adaptation.

I love the font anti-aliasing in Chrome. The anti-aliasing in 10.10 is too much, like in Safari's browser and I agree in 10.50 it's even worse.

Opera 10.5x seems to be forcing full hinting on Linux. Ugh my eyes!

If you are not noticing any difference, you have probably enabled "medium" or "full" hinting in gnome-appearance-properties. "Light" hinting actually looks better if you are using freetype with the latest LCD patches (shipped by default in e.g. Ubuntu).

hm, of the three provided imo opera 10.50s looks best ... and opera 10.10 looks worst wink anyhow, I think that apps should stick to what the OS has set as hinting level and if opera doesn't do that I think this should be fixed.

What is "easier and softer to the eyes" to you is "blink, blink, rub eyes, blink, blink" to me. This is a matter of personal preference. My problem with your Opera screenshot (and this is the same problem I have on my machine) is "ouch! uncleartype rainbow!" rather than "ouch! too crisp!".

"Fonts too crisp" is not the real problem.

The real problem is that Opera fails to obey fontconfig settings properly.

Fontconfig is the way of setting font rendering preferences for applications on linux/X11. The font settings dialogs provided by Gnome, KDE and other desktop environments are just interfaces to fontconfig. Opera does not obey these settings properly, evidenced by the fact that it renders text differently than other applications.
