Neither snorp nor I can reproduce this, qawanted to get STR that we can use to reproduce.
Unable to reproduce, 06/08 Nighty - Galaxy Nexus (4.0.4), nor my HTC Nexus One (2.3.4). Leaving qawanted to see if kbrosnan or nhirata can repro.
Looking at the log, it looks like a H264 video?
Looking at the log it looks like an Application Not Responding (ANR) in fennec due to running H264 video full screen... not sure if it's because of destroying when it's locked? or OOM issues with screenshots from the H264 video... I can reproduce the ANR by going to : 1. http://www.youtube.com/watch?v=4N2YWRJ-ppo 2. set it to full screen 3. zoom and pan around 4. click on a related link on the right and try to play a vid Samsung Galaxy S II, Beta 6.
1. http://www.youtube.com/watch?v=4N2YWRJ-ppo 2. set it to full screen 3. hit the full screen button again to exit full screen 4. zoom and pan around 5. click on a related link on the right and try to play a vid
easiest way for me to reproduce this is to hit the awesomebar after exiting fullscreen
so, this looks like deadlock. We might need something like bug 680311
What is happening here is that after exiting fullscreen mode, Flash waits for the SurfaceView to be readded to the view hierachy. Specifically, I believe it is waiting for the surfaceCreated() callback to be invoked. Currently we invalidate the plugin which causes Paint() to be called on the next iteration. This is normally where we add the plugin view. Unfortunately, because Flash has us tied up we don't make it that far. This patch calls AddPluginView() immediately upon exiting fullscreen, eliminating the problem. The other changes in the code are mostly housekeeping.

Comment on attachment 631946 [details] [diff] [review] Avoid deadlock when exiting fullscreen Flash videos on Android [Triage Comment] If we're going to take this for our 1.0 release, this is the beta to do it in. Our ratings may suffer if we introduce a new regression, but we can always update if necessary. Hopefully QA will find any regressions ahead of beta sign-offs as well.
This seems to have caused a small Talos (SVG) regression. Was that expected?

Issue is no longer reproducible on Nightly 16.0a1 2012-06-19. Aurora 15.0a2 2012-06-19 or Firefox Mobile 14 beta 7 on HTC Desire running Android 2.2. Exiting youtube fullscreen no longer blocks the device use. Closing as verified.
