I've seen this in crash automation on several other urls but this one is most reproducible. All branches.

I can't reproduce after 15 min of playing. The user configuration such as graphics drivers or security software is likely important.

This was on a Windows 7 32bit ESX vm fwiw. The hang reproduced in an opt build within 3-4 minutes for me.

Another example after several minutes on an vmware esxi vm:

Top of Flash stack:

 	KiFastSystemCallRet 	:
1 	NtGdiBitBlt 	:
2 	BitBlt

But the report claims that the process is not using any CPU at the time of the hang. Is the FlashPlayerPlugin.exe process using any CPU when you see this, just checking in the process manager?

I'd be willing to bet that this particular report is graphics-related and probably not a high-priority item for us or Adobe.

I have two FlashPlayerPlugin processes. One is consistently 0%, the other fluctuates in the low single digits. It appeared that at the time of the crash the active process was using > 0%.

Can you repro with Flash 11.9.900.152?
