Error #3694 After locking the computer

[markknol]

When I am developing and testing Flash game in the browser, then lock my computer (in Windows) and then unlock, I get this error:

[Fault] exception, information=Error: Error #3694: The object was disposed by an earlier call of dispose() on it.

This causes to freeze the browser when you have the FlashDevelop debugger enabled.
Would be helpful if this could be fixed.

Looks like a Stage3D context loss. They're annoying, but you can handle them by watching System.hasGPU.

That said there may need to be more testing to make sure Flambe never throws this Error, and thinking about how we can make recovery automatic. I don't want to keep textures in memory, but maybe it's possible to automatically redownload them and update in-place.

Any ideas on this? It also seem to happen on Android. It would be nice if there was a integrated solution for this.

Tried to do some fixes on this again, I would not mind to restart after context lost. I listen to System.hasGPU, and dispose everything on stage and memory, still get this error

Error: Error #3694: The object was disposed by an earlier call of dispose() on it.

It is needed to add checks before accessing some context stuff. I actually managed to implement this for stage3d (didn't bother with webgl). I will try to clean it up and upload it to my fork, making a pull request.

@Antriel please do!
