           Summary: REGRESSION (r102809-r102985): ClicktoFlash drawing of
                    old style youtube embeds missing until resize
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: http://forum.dvdtalk.com/11092085-post1.html
        OS/Version: Mac OS X 10.7
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering

First the ClicktoFlash extension needs to be installed.

Whether I'm set to allow flash from www.youtube.com as a source or not in ClicktoFlash, the provided page will load with empty white space where the youtube video or ClicktoFlash placeholder should be. Then if I resize my window, the missing youtube embed or ClicktoFlash placeholder will then appear. Seems a relayout causes the OBJECT/EMBED or placeholder to now render.

Note that it works fine without ClicktoFlash, but also used to work with ClicktoFlash in r102809 and earlier. There was a nightly (r102930) between my range that I wasn't able to fully confirm because the page would crash 3 times in a row and then show the video embed with that version.

Here's that crash thread in case it has bearing even though the current nightlies no longer crash.

(Oddly while writing this report, Webkit became unresponsive and I noticed my Web Process was using over 9 GB of RAM forcing me to take a quick screenshot for retyping and then force quit Webkit... maybe loading and reloading that page also causes a huge memory leak as well. I'll need to see if I can reproduce it)
