I'm experiencing heavy video stutter in fullcreen mode (what looks like only 2-3 frames per second, audio plays fine), on a Macbook Pro late 2008 running OS X 10.7.4, on FF, Chrome and Safari. Playing within a window presents no problem though. We haven't been able to date the start of the problem (as it is my wife's MBP and she made do with the problem for some time before I noticed it), but it is several months, ie dating to before release 257.

We have another Macbook Pro early 2008 running the same OS and same browsers and it is not experiencing the problem.

I have uninstalled Flash several times and reinstalled with no apparent effect.

Weirder still, I have tried to unsintall the latest version, and tried each release back to 10.3 (ie with some that must have worked at some point) but the stutter persists with ALL VERSIONS. I did reboot between installs as advised in the archive version notes.

Why hasn't there been any new updates to this problem?  This is beyond ridiculous!! 

This Update did not solve any of the problems of Flash Version 13.

I use Firefox 14 at the moment. But I had the same issues with Firefox 12 and 13. I definitely can say that the problems began since I have installed Flash Version 13.

Only a downgrade to Version 12 has solved the case.

My problems in particular are that whenever I try to maximize a video in a Flash-Player (e.g. Youtube, twitch.tv, own3d.tv) the plugin crashes. Further I have performance issues with these videos (low frame rate).

I have to use Opera instead where everything runs smoothly.

And its interesting to mention that I have only problems on my rather old desktop pc (AMD Athlon X2 4600+, 32 bit Windows 7). I am running another laptop (Intel Core 2 Duo T9300, 64 bit Windows 7) where I do not have any porblems in firefox at all.

I use exactly the same plugins in firefox on both, the desktop pc and the laptop.

Okay as I have been using flash player 11...I use google chrome an ie once in a while...still get the gittery and slowdown glitches in gaming...war commander is one I play most of....CPU usage is up and down...which make it gittery to play...if you have any suggestions it would be helpful, thank you for the resent reply

Unfortunately, the 11.3.300.265 release has not solved my choppy audio problems in Firefox 13 with Windows XP. In fact the problem now appears to be somewhat worse because the audio gaps are longer. The details were reported in bug #3214996.

My company has written a digital signage application that runs in flash and includes a video player component that needs to run 24/7. The application ran fine on older versions of the player using Snow Leopard on the mac mini. Since the advent of Lion, flash video on the Mac mini is too unstable to be useable for this application. We have tested on a variety of browsers and the results are the same.

After a couple of weeks of testing we have isolated two separate (though possible related issues):

1. Using stageVideo/GPU acceleration on Lion, video will freeze after roughly 2-5 hours of play. If the video freezes midway in the movie, that main application thread will actually still be running (timer events fire, etc). However, if the video freezes at the end or if code is integrated to detect the freeze and move on to the next move, as soon as the netstream object is referenced in any way [via the dispose() method, for instance] the main application thread itself will die (silently with no errors thrown).

The video freezes seem to be correlated to the following errors being logged in /var/log/syslog

Jul 9 05:09:02 XpoLDS128_131 PluginProcess[59422]: AVF error: Dithering:: pushPicturePrepareCmdOOLD, CVPixelBufferPoolCreatePixelBuffer

Jul 9 05:09:02 XpoLDS128_131 PluginProcess[59422]: AVF error: OOLD cmd_info->args == NULL

Jul 9 05:09:27 XpoLDS128_131 PluginProcess[59422]: AVF error: faild to create pixel buffer

2. If stageVideo is disable and a traditional video object is used, the video loops will run much longer -- running for 20-40 hours before freezing. While the incidence of failure is less frequent, it is still not acceptable for a 24/7 application. Entries in /var/log/syslog also suggest issues with the interface to the AVFoundation [although this is just a correlation -- not necessarily a cause and effect]:

Jul 13 13:03:46 XpoLDS128_131 PluginProcess[471]: AVF error: scheduleDecodeFrame codecBadDataErr nal_size err : acc_size = 156663, datasize = 156663, nal_count = 0...

If anyone has had periodic video freezing on Mac OSX Lion, your issues could be related to mine. I opened up a bug case on the GPU issue a week ago, but it has yet to be picked up.

Please vote the issue up if you are having similar problems:  https://bugbase.adobe.com/index.cfm?event=bug&id=3278625

Audio is force-played through all speakers on my 5.1 speaker setup after the latest .265 update. Reverting to an older flash player version fixes the problem so the newest update is what causes it.Basically even in the older flash videos on youtube, which certainly have no 5.1 audio, the sound comes from all five speakers even though it shouldn't. Also, the overall gain is quite a bit higher and the bass boomier when compared to the previous flash player version.

Specs: Win7 x64, X-Fi Titanium Fatal1ty, Newest Chrome and IE

It updated Flash to 11.3 in the background after I downgraded it for the reason I was getting sound distortion on YouTube. I was told it was my computer, my issue, but it soon became a bug.

Surely enough this latest version has the same distortion issue on my computer [Windows 7, Firefox, x86]

I have downgraded to 10.2 until I know for sure the new Flash is going to keep my Audio playing normally [It sounds like gain is turned up too much] using YouTube.

Using 11,3,300,265 on Opera and Windows 7 and it's not remotely fixed the severe stuttering and lack of sound.

Hi Adobe

Theres a problem with Logitech Sound devices, it will place a heavy bias on the right hand side with all flash instances, reboot, reinstall all tried both of chrome flash and logitech drivers.

Please address
