STR:

1) Open 2 tabs with web content.
2) Switch between tabs.

Expected: Content of selected tab is displayed.
Actual: The Content of the previous frame is displayed for a very brief moment causing the content to appear to flash.

It looks to me like content of the selected tab needs to be recomposited or at least cleared sooner and that the flash of previous content is just what was last composited to the surface.
I've seen this a lot as well, we should definitely fix.
