I don’t seem to be able to reproduce with r58691, but maybe I don’t understand which frame is supposed to have issues. I can successfully scroll the preview pane below the message list, as well as a message in “full view”. Problem still exists with r58691 for me. An additional observation, though I'm not sure it's related to this problem: The console reports an error that don't appear in the earlier version (r56855): "Unsafe JavaScript attempt to access frame with URL http://us.mg2.mail.yahoo.com/dc/launch from frame with URL http://ad.doubleclick.net/... very long param list ...?. Domains, protocols and ports must match." Seems like a security restriction that is now being triggered which may or may not be valid. Perhaps a screenshot, possibly annotated, will help me understand how to reproduce the problem. mitz: Your testing was correct, so I don't think a screen shot will help. I did some checking and found there's another requirement to see this problem. This problem happens with Adobe Flash Player 10.1 RC2 installed or Adobe's Flash Player "Gala" (H/W acceleration) Preview Release (which Adobe's documentation says is based on 10.1 RC?). (I was trying out the "Gala" h/w acceleration release days earlier and hadn't made the connection to the problematic behavior prior.) I do not see the problem with Adobe's Flash Player 10.0.45.2 (current production version). Thanks! I can reproduce with Flash 10,1,81,3 (the “Gala” preview). Created attachment 54999 [details]

Patch
This does not fix issues with scrolling PDF documents in iframes in composited layers. Includes a manual test. I don’t think an automated test is possible.

Patch
r=me but can't we have a Layout Test that loads, waits for a draw, then scrolls, then is snapshotted?
