FP10 GPU wmode resizing issues

Anybody notice any issues when resizing windows that are embedded using the new “gpu” wmode? Like a noticeable lag and some scaling issues for about a second before it fixes itself? Its not a big problem but it is a lot less smooth than previously…

Edit: I threw together a quick demo so you can have a look. Any ideas on a way to fix it? I’m working on a site and it really has to use the new gpu wmode since it improves the performance quite significantly, and although this isn’t a massive problem if theres any way to improve it would be great to know.
