Status: RESOLVED WORKSFORME

(Core :: Web Painting, defect)

Notice how the plain text is crisp but the text with a non-integer transform + a filter is blurry.

This is happening on a real-world website: go to http://www.dailymotion.com/ and click on the top right "login" (or "connexion" in french) link.

Just checked in stable 44, it's affected, so it's likely not a regression.

Chromium (I tried v48) does not seem to have the issue (I used `-webkit-filter` instead of `filter`, so the testcase here is not directly usable).

Aurora 49 still affected.

Triggered by Bug 948265
(Not a regression, the problem started since supporting of the css blur filter)

Julien, the testcase looks OK to me on my Win11x64 Nightly.
Can you still repro?

I see like you, that the testcase looks OK for me as well. I'm testing on Release on Linux. I think it's good to close now.
