Comment 1

[Bas Schouten (:bas.schouten)]

Direct2D vs. non-Direct2D regression is related to the fact we no longer have GDI DCs for the plugin to draw to directly, causing us to go through a more complicated drawing path, 2 possible methods of mitigation are:

- Jeff tried making Direct2D interop work well, but I believe there were a number of (possible non-surmountable) issues.
- Avoiding alpha recovery if the flash plugin gives us proper alpha values in a plain DC.

I'm not sure if both are still valid now that we have asynchronous painting.

Comment 2

[IU]

I experience this issue on Windows XP, so any solution should take into account platforms that have absolutely no support for Direct2D.

Comment 3

[[not reading bugmail]]

Well, this is no ordinary web page, just looking through Page Info Media.. 

This page is got a lot of junk on it, and I mean a lot of images, large images, both super long and skinny and a lot of large background images, some I'm not sure if they are even visible on the page.

There also appears be heavy javascript and a scroller in the middle of the page, and at least 2 flash videos with plenty of divs mixed in.
