If this is not reproducible in 49.0.1 and *is* reproducible in 49.0.2 RC then it should be a pretty small range. Can you bisect that range please?

	Kartikaya Gupta (email:kats@mozilla.staktrace.com)
	Comment 2 • 8 years ago

Also ni? to :lizzard as FYI as this might be a regression in 49.0.2

From [1] 49.0.1 build 3 is at cset 2d931a5eaf8aeee925eca2aea42582a1fb9793c8.
From [2] 49.0.2 build 1 is at cset ea6157b86ae2b200ca3433d462516bf75559e056.

That gives a pushlog range of http://hg.mozilla.org/releases/mozilla-release/pushloghtml?fromchange=2d931a5eaf8aeee925eca2aea42582a1fb9793c8&tochange=ea6157b86ae2b200ca3433d462516bf75559e056

[Tracking Requested - why for this release]:
New regression identified in 49.0.2-build1 (20161018030522), that might affect other websites as well.

	Comment 5 • 8 years ago

This is Flash video (not <video>).
This is almost certainly related to the async painting feature that we already shipped via system addon to 49.0.1 and also enabled by default in 49.0.2.

Matt, can we figure out whether we're sending the wrong visibility signal to Flash, or whether they are incorrectly not sending us frame updates?

I personally do not believe that this should be considered a stop-ship issue.

	Kartikaya Gupta (email:kats@mozilla.staktrace.com)
	Comment 6 • 8 years ago

Moving to plug-ins based on comment 5.

	Matt Woodrow (:mattwoodrow)
	Comment 7 • 8 years ago

I don't know much about async painting of plugins, maybe Jimm is better?

	Jim Mathies [:jimm]
	Comment 8 • 8 years ago

I'm not having any luck reproducing this in Nightly. I see some weirdness on the cnn video when scrolling, but that appears to be a side effect of the site's treatment of the video when you scroll the main video frame out of view.

Can anyone else reproduce? If so, can you try setting dom.ipc.plugins.asyncdrawing.enabled to false, restart, and see if the issue goes away.

	Jim Mathies [:jimm]

Also, if you can reproduce, please post your about:support text so we can confirm your flash version.

I tried the STR on the cnn video link from comment 0 in my win10 laptop on 50.0b8 and I can see a smooth audio/video playback. My user agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:50.0) Gecko/20100101 Firefox/50.0

	Comment 11 • 8 years ago

The issue is no longer reproducible with "dom.ipc.plugins.asyncdrawing.enabled" set to false. 

Also, I want to mention that I have Flash Player 23.0.0.185 installed.

I can reproduce this on nightly x64, Flash 23.0.0.195.

	Camelia Badau [:cbadau], Desktop QA Reporter
	Comment 13 • 8 years ago

The issue is reproducible on 49.0.1 with Asynchronous Plugin Rendering shipped as a system add-on. 

Therefore, it is not a regression since the bug is also present in release.

	Liz Henry (:lizzard) (relman/hg->git project)
	Comment 14 • 8 years ago

I don't think we need to hold up the dot release for this issue. 

Though that may still be a regression from the system add-on (i.e. from enabling async rendering) as Benjamin mentions.  
Jimm can you help find an owner for this? May be good to try to fix it for 50 though we are late in the cycle.

I can reproduce this issue with the following specs:

Asynchronous Plugin Rendering is set to true.

	Comment 19 • 8 years ago

We've reverted the pref dom.ipc.plugins.asyncdrawing.enabled to false in 50.0b10. 50 should be unaffected now. Wontfix for 50 (when the pref is set to true).

I've tested with the try build (https://bugzilla.mozilla.org/show_bug.cgi?id=1312242#c26) on Windows 7 x64: the issue is NOT reproducible on this try build, video plays without issues after exiting full screen and scrolling the video in and out of view.

I'm making the release status the same as bug 1312242 (with a ? for 51 since that bug's patch may still be uplifted).

	Tracy Walker [:tracy]
	Comment 28 • 8 years ago

This is not fixed by 1312242.  In latest Nightly 53.0a1, 20161201030205, after coming out of full screen then trying to scroll the page, the video still hangs while audio continues on.

Too late for a fix for 53, fix-optional for 54, minor carryover regression.

	Comment 30 • 7 years ago

The NASA video in comment 0 now uses HTML5 video.

The CNN video is still Flash, but I am not able to reproduce the bug with 64-bit Firefox 53 or Nightly 55.

	Chris Peterson [:cpeterson]
	Comment 31 • 7 years ago

I am using Flash version 26.0.0.115 Beta, which might include some async drawing fixes from Adobe that are not in Flash 25.
