I tested the following wikis too and most of them had the hinting issue.

Sanskrit (Also uses devanagiri I suppose)
Odia
Telugu
Kannada

The readability factor has to be determined by user who understands the script, the importance of hinting to differentiate similar looking chars etc.

This issue needs to be clarified a lot, and ideally on an issue by issue basis.

Yes, Sanskrit also has the issue with Lohit font. Also, there were similar (minor) problems with the old font as well (I'll save that for another bug).

Seems to be still valid, attaching a screenshot of http://hi.wikipedia.org/wiki/%E0%A4%AE%E0%A5%80%E0%A4%A1%E0%A4%BF%E0%A4%AF%E0%A4%BE%E0%A4%B5%E0%A4%BF%E0%A4%95%E0%A4%BF with high zoom on Firefox 15.0.1 on Fedora 16 Linux.

Can you annotate in screenshot where you see text with issues?

Uhm, I just realize that the extremely blurry text IS in fact an image file. Sorry, my fault.

Srikanth:
Could you clarify where exactly the issues are located, in case they still exist, and which browser and version is used?

The problem is related to how WebFonts are hinted on Windows XP / IE combination (sometimes even Ff,chrome) when the font does not have hint information in them. I could not get a screenshot now, but I am pretty sure the issue exists.

There is nothing we could do to this except making non Lohit font as default font when they are available. Marking it as upstream

Marking it as upstream

Errm, upstream for which project exactly? I'd prefer to have existing upstream bug reports when adding the "upstream" keyword. :)

It's not a preference, it's a requirement.

It looks OK to me now. The WebFonts extension was retired. If there are still hinting problems, please reopen under Universal Language Selector component.
