To help developers who are not very familiar with the Kannada writing system, please give a specific example of a word that shows the problem, with screenshots showing the difference between correct and incorrect display. Thanks!

Attachment: Screenshot showing the difference

New screenshot is added showing the difference between Google Chrome rendering and Firefox rendering. the same applies to menu UI text.

I'm usnig Linux, I tested same text with different font size, this issue appears only for few font sizes, for others it works without any hiccup. so perhaps its anti-alias issue related to Linux?

As all menu text font size in firefox dev release is bigger than stable release, and as i mentioned earlier, issue appears only for perticular font size. This is there in Dev release menus but not in stable menus

It looks like this could be a freetype hinting issue, maybe dependent on the specific font hinting/rendering settings that are in effect. What font is being used for the Kannada text on your system?
