1618052 - Mozilla freezes on video playing

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, defect, P3)

Description

[Mark A. Hershberger (hexmode)]

After reading about the snitch the glitch challenge, I decided to enable WebRendering.

I haven't seen a glitch like the black boxes being talked about there, but I have had my laptop hang up on me a few times since, always when playing a video. The sound continues, my mouse continues to work on screen, but every thing else is frozen.

Today this happened a couple of times after my computer had been running for a while and I clicked on an embedded video in my Twitter stream. I initially tried the same video again, but was not able to reproduce it. And then the hang happened again today after my laptop had been running for a while under very similar circumstances.

I noticed that one process ("GPU ...") takes up a lot of CPU when this happens.

Linux, Gnome, FF nightly, Intel graphics.

hexmode, can you upload about:support to this bug? Thanks.

This sounds like it might be driver bug so it would be good to know kernel version and mesa version. Also it may be worth checking dmesg after the hangs to see if anything shows up there.

I'm watching the umpteenth Democratic debate right now on cbsnews.com and it happened again since writing the initial report. I've not had the same problem under Chrome. I'll let you know if it happens there or not tonight.

(to be clear, I started watching with firefox and my laptop froze up. I'm trying to watch under chrome since my experience there is better. Maybe i should try without webrendering enabled in ff.)

Comment 6

[Mark A. Hershberger (hexmode)]

It happened again, but I'm a little leary of putting all the blame on the video driver just yet since I was skimming twitter in FF while watching the debate in chrome. I'll turn off FF completely and see if it happens again.

And, even though dmesg hasn't been logging like I think it should, I'll try to get those logs, too.

Comment 7

[Mark A. Hershberger (hexmode)]

It has been happening too much, so I'm switching off of the nightly. I have dmesg logging now, so we'll see if this happens, and, if it does, what dmesg captures.

Comment 8

[Robert Mader [:rmader]]

Mark, does this still reproduce for you?

Comment 9

[Mark A. Hershberger (hexmode)]

I'm running nightly (again) and haven't seen this in a while.

Thanks!
