After Flash Player 10.1 update, BitmapData copying no longer works?

Question

Hi,
I recently updated to the 10.1 flash player. However, after the update - none of the application within which I'm using the BitmapData class (AS 2.0) work anymore. The source graphic loads fine, but the .draw procedure that used to work fine no longer works at all.
I'm definately not alone on this issue, as a number of my colleagues in the office have reported the same behaviour. Once I uninstalled the 10.1 update and reinstalled an older version 9.x update, the BitmapData copying works fine again.
Bit stumped on this one. Anyone else experiencing this issue?
An example of one of the SWFs that use this facility is shown at the top of the page here (in the grey box area):

Here's a screengrab of the issue in question:
I'm running Windows 7 (32bit), this issue seems to affect Flash Player in all browsers (tested in IE 7, IE 8, Firefox, I haven't got around to testing it in Chrome, Safari or Opera etc..).
Any help would be appreciated, thanks!

Thanks for the reply, but I think the problem isn't as simple as you suggest.
Firstly, I'm not sure why I would need to update my video drivers to the latest version, when clearly this functionality was working 100% correctly before the Flash Player update. And on this same note - what about the many devices that run OEM hardware (i.e. laptops) that have pre-baked drivers that are never updated? (Thanks, nVidia!)
Secondly, I'm pretty surprised that the suggestion was made to disable hardware acceleration. Why would this be necessary? I  understand that Flash Player ties into the GPU for some tasks - but as far as I'm aware, the visuals we working in one version (presumably with the default hardware acceleration enabled), and now - they are not. Does this imply specific changes to the hardware acceleration code used in Flash? Or is it, as I suspect, a more serious problem with a fixed-bug that has unravelled another part of the player.
The main issue I have here is that we now have many clients complaining that their flash clips we've made (that use similar functionality as that linked to above) no longer work - and they see the same white screen.
I appreciate your insights here - but you must appreciate that we can't just start emailing all our clients saying, "Oh, by the way - can you go into 'x' control panel and disable your flash hardware acceleration, oh and whilst you're at it - download and install the latest video drivers for your machine.". They'd have a conniption - and we can't expect our clients to just do all of that for the sake of a mistake made by Adobe.
You mentioned that this isn't the right forum for raising these specific issues - although I can see that mostly all bug issues seem to end up here. Would you be so kind as to point out where I should be posting this issue, so that I can bring it to the attention of the right people?
I was hoping more people would notice this, but I appreciate that it's more of a developer-specific problem.
