Details

When e10s is enabled there are very strange artifacts when scrolling sites with Flash videos. Video element does not follow scroll position and sometimes displays partial content. Occurs only while scrolling with mouse wheel, scrolling with scrollbar behaves a bit better.

Example site: http://www.dailymotion.com/video/x306zew_dc-shoes-robbie-maddison-s-pipe-dream_sport

See attachments: one with e10s enabled, the other with disabled.

Windows 10 Pro final (pl), Nightly 42.0a1 (2015-08-09) (locale: pl), Adobe Flash Player 18,0,0,209.
