[Note]: - please check that "layers.gpu-process.max_restarts" integer preference is set to "3" (from about:config) - please check that the "Use recommended performance settings" checkbox below the "Performance" is checked (from about:preferences -> General) [Affected versions]: Fx 55.0a1 [Affected platforms]: Windows 8.1 x32 Windows 7 x64 [Steps to reproduce]: 1. Launch Firefox. 2. Go to a youtube video. 3. Terminate the CPU process from about:support . [Expected result]: A short glitch, afterwords the video plays smoothly. [Actual result]: The video remains in an infinite loading state. [Regression range]: Will return with the regression range as soon as possible. [Additional notes]: A gif with the issue: http://imgur.com/a/CQR6A .
Summary: After terminating a CPU process youtube videos remain in an infinite loading state → After terminating a GPU process youtube videos remain in an infinite loading state
It'd be also good to know if pause/play or reloading the page fixes the problem.
Also, can you (restart not required) set layers.gpu-process.max_restarts to 0 and repeat the workflow and see if the problems are gone or different?
I tested with the pref "layers.gpu-process.max_restarts" to "0" using Fx 55.0a1, build ID: 20170605030204, on Windows 10 x64, Windows 8.1 x32 and Windows 7 x64. This issue is not reproducible under these circumstances. Cheers!
David, let's reset this preference back to the default (I never know if that's 0 or 1), so that we never restart to accelerated beyond nightly. It'll give us a chance to sort out the issues, but it'll stay on nightly until we're sure we're good and sort out the telemetry/etc. we need for making the right call. [Tracking Requested - why for this release]: This should block 55 - we don't want a preference where we have some negative anecdotal, and no telemetry/crash evidence to tell us otherwise.

Sounds good. I'll file a new bug so we can track this issue separately.
Depends on: 1370621
This functionality will be off in 55, so no need to track it for 55.
Pushed by firstname.lastname@example.org: https://hg.mozilla.org/integration/mozilla-inbound/rev/b6314a490ce8 Only restart the GPU process multiple times on Nightly. (bug 1369097, r=milan)
Hi, This issue doesn't seem fixed to me. The actual result is different now but the steps for getting there are the same. If the GPU process is terminated while a YouTube video is playing an error message appears and not even a refresh can make it work. A browser restart is needed for watching the clip again. This only happens on 32 bit builds of Firefox. Tested on: - Windows 7 x86 & x64 - Windows 8.1 x64 - Windows 10 x64 Please see the attachment for the error.
