I've had a handful of Flash crashes today while trying to watch both the weekly public project meeting and then the MoCo-internal monthly update.

All of these happened when clicking the various player controls in the VidyoReplay stream.

I'm using Flash 11.3.300.270, and Protected Mode is enabled.

I have seen hangs using almost exactly the same STR but not these (generic) crashes. Are you experiencing a hang before the crash comes up?

Yeah. I click one of the player's buttons, Firefox locks up for a few seconds, then crashes.

Is it still happening with 11.4.402.265?

I don't seem to be crashing or hanging, but there's no livestream currently, so I'm just watching a pre-recorded video on VidyoReplay. I never tried using a fully recorded video back when I reported this, so I'm not sure if there's something different about it.

Did any one experience the crashes/hangs specifically on live streaming lately? Marcia tried it on a pre-recorded video with latest Flash/FF version and we are unable to reproduce it.

If you find yourself able the reproduce the issue, checking the following things would be very helpful: 

1.) The output of dxdiag. 
    (We'd like to know what graphics card and driver version you're running)  

2.) Does disabling hardware acceleration in Flash resolves the issue?  
    (Right click on the SWF, choose settings, uncheck Enable Hardware Acceleration)

3.) Does installing the current available graphics drivers for your system resolve the issue?

Any improvement with 11.5.500.80?

Comment 8

[Jeromie Clark]

I'm not seeing any reports of it, but it's possible that the signature may have shifted.

Only one hit so far for 11.5.500.80.

Comment 11

[Jeromie Clark]

When I deobfuscate the stacks, I'm not seeing anything that stands out as unique from reports generated from the generic crasher associated with this signature.

Did you guys have any success in reproducing this?  If so, would it be possible to get a URL that demonstrates it?

I haven't seen this recently, so I'm going to mark it WFM and reopen later if necessary.
