749268 - Fonts look fuzzy and blurry until hovered. (persisting since 14 branch)

Status: RESOLVED WORKSFORME

(Core :: Layout: Text and Fonts, defect)

Description

[Rakshith]

Attachment: the circled text outline (colored, zoom into the image to notice.) is the result of hovering on it. the rest is blurry because they aren't colored.

The words of the line where the mouse icon is placed (has to be on any word of the line) turn sharp. The rest words on the page remain fuzzy. The line which got sharp after mouse was hovered on, retains fuzziness after sometime as it is unhovered by the mouse. However it can vary too to what length the amount of words that sharpens due to hovering over effect is, and also not everywhere do I see this problem. This blurriness in font is noticeable on Facebook and "about:config" in Firefox and text input fields (Bugzilla included) to my knowledge. I suspect the size of the text and my custom gfx configs have something to do with it.

Here is my about:support clipboard copy.
