Having tried to replicate the issue with a variety of content on
Netflix, it looks like the issue arises with only specific content.

I think this must be because I checked the box saying the bug might affect
a lot of other users(security bug). The content is the same as what is
posted on launchpad.

This was due to some confusion while trying to file the bug via the mobile
phone. I thought I was reporting a website (Netflix) messing with the web
browser.

Just a warning, but unexpected, so we want to have a look at some point.

I am able to reproduce the messages by hovering over various programme titles in Netflix and then refreshing the page.
I get:

Around the same time, the browser tab became graphically unresponsive (blank contents).

Hi James, as explained above the messages are just warnings, so something else must be going wrong. We'll need more details about your configuration, e.g. which distribution are you running? What graphics hardware and drivers do you have?
Could you try to run Firefox with ```MOZ_

Hi Gian-Carlo - this is on Debian 11 (bullseye), using the Intel i965 VA-API driver (and media.ffmpeg.
I'm not super keen to attempt repro without the sandboxing in place at the moment but I'll add details if & when I do.

I've failed to reproduce this with Nightly and Debian unstable; I get the warnings about `/sys/devices/
The browser tab locking up is unexpected, though — even if the media plugin process crashes or hangs, the media subsystem is pretty good about doing everything asynchronously. If try playing something and then kill the `gmplugin` process, it stops playing and I get an in-content error that “something went wrong with playback”, and then it won't play anything until I reload the tab; that's all more or less what I'd expect. If I `SIGSTOP` the process, a few seconds later the audio stops but the time in the UI keeps advancing (and if I `SIGCONT` it, it will resume playing where it left off, which is no longer where the UI says it's playing from; that's an interesting bug but it might be Spotify's and not ours). But, no sign of the content process locking up or crashing.
In Mozilla Bugzilla #1783163, Jay+bz (jay+bz) wrote : | #15 |
The tab doesn't completely lock up in this case - media continues to play audibly, and keyboard input is possible within the browser -- although invisible -- until the window and tab are visually obscured and then re-opened.
In other words: after the issue appears, switching to a separate application and back again permits a single frame of the browser contents to render, but after that point they remain visually static (until the next manual refresh occurs).

Ok, this happened to me again a few moments ago while browsing GitHub, and this time Spotify web player was not open (so my apologies for mistaking that as the possible cause).

Clear a needinfo that is pending on an inactive user.
Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as `INCOMPLETE`.

This looks like https:/ /bugzilla. mozilla. org/show_ bug.cgi? id=1712506, but according to that upstream bug the issue should have been fixed a while ago.
