Lag when using Steam Overlay

Hello,

I've opened an issue on the github and figured I would post here as well:

https://github.com/Gamua/Adobe-Runtime-Support/issues/505

As stated there, I've been noticing a ton of lag and freezing while trying to open the Steam Overlay over an AIR application. Forcing the old GPU mode makes it usable, but still pretty awful. Our application relies on in-app purchases through the overlay to make money, so obviously having a near-unusable interface is gonna turn a lot of potential customers off.

Has anyone else run into a problem like this? I've tested the last 3 releases of the SDK as well as the old 32.0 version and have the same issue.
