For pure entertainment value, go to http://caniuse.com/, give the Search
field focus, then scroll the page down just enough to hide the search
field… and watch the entire page of text toggle between smoothed and
not, every half second. Coincides with the blink rate of the insertion
point.
Didn't know if this would help with diagnostics, but it's just too
awesome not to share. (Yes, I'm easily entertained.)
Haven't seen this on other pages yet…

Matt/Roc - we've seen a lot of duplicates of this bug filed for FF18.
The user impact here does not seem severe (and there were no reports
pre-release), so we're leaning towards fixing for the first time in
FF19. Thoughts on the risk of uplifting bug 806099 to FF18?

The impact may not be severe for the average user or those with certain
monitor resolutions, but for those of us doing UI design, it's a bit of
a PITA. I for one would love to see this fixed soonest.
But I'm not your flavor of developer so I certainly don't know what it
will take to nail it. Thanks to all of you for your great work!

It is not zero-risk, although the patch has been on trunk for a while
and no regressions have been reported other than one isolated
performance issue.

Same here.Fonts are very blurry on certain sites (gmail, lequipe.fr) as
shown in attachment. Happened since updating to firefox 18. The loss of
sharpness is very annoying visually.
