I see the flash in chrome (highlighting some random text at the end). I doubt there is anything we can do about this and bet it will be gone in some future release. And back again in some future future release.
I don't see the flash in the latest firefox. I liked chrome for years, but am in the process of shifting my own normal use to firefox. Firefox is more plodding, but there is some truth in the saying 'use a browser built for browsing rather than a browser built for advertising'.
