User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/17.0 Firefox/17.0 Build ID: 20120827030549 Steps to reproduce: Navigated to weatherspark.com, with a fresh profile. For example: http://weatherspark.com/#!dashboard;q=Corvallis%2C%20OR%2C%20USA Actual results: Input lag is evident in the browser window as you move the cursor over the temperature graphs (the crosshairs lag considerably following the cursor). Expected results: There should be little if any lag. This seems to have started with the new Flash 11.4 update (I don't recall it being there with 11.3), but it might also be Firefox-related. There does not appear to be any problem with Flash 11.4 in Chrome (21.0.1180.83) or IE9.
I tried with Flash 184.108.40.206 and FF17, there is no lag. So the issue is probably with new Flash 11.4.
Per a suggestion from the MozillaZine forums, I tried disabling Protected Mode in Flash and that fixed the problem. So it looks like there is a problem with the interaction between FF and Flash's Protected Mode (again...).
anyone else able to reproduce? i am unable to reproduce testing, Firefox 14,15 and 18 using flash player 11.4.402.265. would you mind to post your dxdiag output and a video if possible? thanks...
unable to reproduce on Firefox 16, aurora, also. where can i download version 17?
Here: ftp://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-aurora/ (Firefox 17 builds)
thanks for the link. unfortunately, i'm also unable to reproduce on Firefox 17.
Created attachment 656234 [details] DxDiag Here's my dxdiag output. I'll work on seeing if I can put together a movie.
thanks. placed a request to our lab services for a similar radeon card. i won't have access to it until thursday. i'll post back then.
Here's a Youtube video of what I'm seeing. It's actually worse than it looks in the video, since it makes the whole Firefox interface slow down (when I mouse over the Flash content and then off to the FF interface, it takes a while to catch up). http://youtu.be/pp-aEIc-Di0?hd=1
As a comparison, this is what it looks like when I set ProtectedMode=0. http://youtu.be/-hS6-8jECs0?hd=1
ok, i am able to reproduce the issue on Win8 Firefox 17.0a2 Flash Player 11.4.402.265, but not in Firefox 15. i am assuming the issue may be a regression in Firefox. can you verify, if it's not reproducible for you in Firefox 15? thanks...
I noticed following strange behavior in Firefox9.0.1 - Nightly18.0a1, Windows7 x64, Flash Player 11.4.402.265. When reproduce the issue, Right click on the chart(flash)and select 1st menu item to popup setting dialog of flash, and close it. Then, the problem is gone unless I change the tab or window.

I just checked it out and the problem definitely still exists for me in FF15. And it goes away with ProtectedMode=0 in FF15 as well.

And, yes, I can confirm this behavior as well. If I open the "Settings" dialog for Flash Player, choose a tab and then click "Close", the lag goes away temporarily until I mouse out of the window.
thanks everyone. i must have clicked on the content when i was in Firefox 15. as stated, clicking or right-clicking the content temporarily resolves the lag. we are tracking the issue internally in #3325048...
our internal bug has been closed verified fix in 11.5. the next beta refresh should pick up the change. for those wanting to test, please grab tomorrow's refresh build here: http://labs.adobe.com/technologies/flashplatformruntimes/flashplayer11-5/
Adding qawanted to confirm this as fixed as well.
I'm closing a lot of bugs which are filed as Adobe Flash bugs which are either irrelevant, not actionable, or not serious enough to track in the Mozilla bug tracker. For the most part, Flash bugs should be filed in Adobe bugbase, and we'll only track a few highly-critical issues in the Mozilla tracker.
