Similar to Bug 1559284, I have a dual monitor setup, and when a youtube video is playing in the non-focused monitor it freezes when it doesn't have focus.

Hmm, looks like this happened with WR disabled. Enabling it fixes the bug.

Is there any chance you could use mozregression to figure out if/when this regressed?

Thanks!

I'll try at some point. I believe that I had used my system the same way about a week ago with no issue, so it should be fairly fresh.

What version of Windows 10 do you have? 1903?

Yes. Surface Book 1st Gen with Intel and Nvidia

Hello I tried to find a regression but I didn't manage to reproduce the issue on Win 10 on a Dell G3 15 laptop with Intel i5-8300H 8th gen and Nvidia GeForce GTX 1050 with dual monitor setup. Could you please look for a regression for this issue using the mozzregression tool provided in comment 2 because we currently do not have the hardware on which you found this issue.

I don't have that laptop anymore either. Sorry.

Hi, Since this issue does not reproduce on our end and the reporter is unable to reproduce it on his end we can remove the regressionwindow-wanted tag from this issue.

Regards,

Attachment: Troubleshooting Information

I have had this issue as well for months - possibly over a year. I can't reliably reproduce it every time, but it happens frequently where when I move a Firefox window to my secondary monitor, the YouTube video will freeze while audio keeps playing. The video will instantly catch up if I mouse over the window (not even changing focus in Windows) or sometimes if I wait it will resume, then freeze again, and so on.

Forgive my ignorance with Firefox's inner workings - I'm not familiar with WebRender. Is this a feature that can be toggled somewhere? What can I do to help test? I will see if I can check out the mozregression tool but let me know if anything else would be helpful. I'll also provide a troubleshooting output.
