After suspending and resuming, flash content is not shown any more

[Teo]

Binary package hint: flashplugin-nonfree

Steps to reproduce:
1) Open a web page containing some flash content, for example a youtube video (but this happens with ANY flash content)
2) Suspend Ubuntu. I do this by closing the lid of my laptop (it is set up to automatically suspend)
3) Resume Ubuntu

Expected: the flash content should be still visible
Observed: a white rectangle is shown instead. The content still responds to mouse events such as clicks, however: you can notice it if the clicks produce sounds or open links in another window. If you click on a FullScreen button (such as YouTube's fullscreen button - obviously you click on it without seeing it), then the issue gets fixed, and after coming back from fullscreen the flash content is shown again.

THIS IS A REGRESSION: this has started happening after upgrading from Ubuntu 10.04 to Ubuntu 10.10

I'll attach a screenshot taken from a youtube video after suspending and resuming
