When going to the page http://www.channel4.com/programmes/4od using the Qt demo broser in Qt 4.5.3 on X11, The Adobe flash plugin will fail to embed properly on the page and will be visible in the top left corner of the page as a rectangle. The Flash plugin is running, but it is in the wrong place and the wrong size. The plugin will only get suck in the corner sometimes, but you will always see it there at some point while the page is loading.
I do not see the problem when using Chromium (18.104.22.168 (Ubuntu build 28248)).
Adobe Flash Plugin version: 10,0,32,18
I couldn't reproduce this.
Andy, can you still reproduce with a more recent Qt version (or with QtLauncher from WebKit trunk, if possible)?
Closing, no problem with trunk for me, Kent doesn't have the problem either.
Andy, if you can reproduce the issue with a recent Webkit, please comment so we reopen the task.
