Status: RESOLVED DUPLICATE of bug 1212813

(External Software Affecting Firefox Graveyard :: Flash (Adobe), defect)

Description

[George Wright (:gw280) (needinfo me!)]

This is reproducible on Linux on Nightly (47.0a1 (2016-02-29))

I visited that page and scrolled. All the graphs on the page flashed whenever the page was being scrolled. This does not happen in non-e10s or on OS X. Haven't tested Windows.
