1360375 - Artefacts when watching videos in the browser

Status: RESOLVED WORKSFORME

(Core :: Audio/Video: Playback, defect, P1)

Description

[marko.filipovic]

Attachment: Printscreen of the artefacts

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170413192749

Steps to reproduce:

1. Open Firefox
2. Go to youtube.com and open any video.


Actual results:

Lots of green splotches over portions of video, other artefacts too. Makes Youtube videos unwatchable. Doesn't appear for example on Vimeo.

I tried:
 - turning off hardware acceleration
 - running the browser in safe mode
 - making a completely new clean profile

Nothing helped. This started happening a few weeks ago.


Expected results:

Videos should have played normaly.

I'm not sure how to revert to the previous version of Firefox, and I also don't know if installing an older version will somehow affect my current installation (though I can try to do it within a virtual machine and see if the behaviour repeats). But I do know that the artefacts in Youtube videos were present in both v52 and current v53.

Can you check https://www.youtube.com/html5 and see whether "MSE & WebM VP9" is available.

Everything listed on the website is checked. Also, the artefacts presist in version 54, and there are more of them than ever. Conversly, this stopped happening on the latest Firefox release for Linux/Ubuntu.

On Windows 10 x64 (where the bug is active), I am running NVIDIA GeForce 1070 with the latest drivers, if that is of any issue.

Right now, my workaround is to open every video in Chrome, which is ridiculous.

Very sorry to hear.
It looks like your card HW features have been disabled due to prior crashes.

Could you try in a new profile? or do a profile refresh (https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings)

Firefox 55 made vp9 hardware acceleration for your graphic card, you should normally see great improvement speed wise (with also a much reduce CPU usage)

So, if I understand correctly, for all 1070 cards Firefox displays these green artefacts?

I already tried both a new profile and profile refresh in Firefox version 53, and it didn't help. I see that on Ubuntu I already have FF version 55, while on Windows I'm on 54. I'll try updating FF on Windows to the newest version and report the results.

Thank you for the information!

Certainly not.

This is the first report we've had with a nvidia 10xx cards (they are brand new)

Yes, please update to Firefox 55, and try again with a new profile.

Confirming that, for now at least, the videos seem to load normaly in Firefox 55, even with the old profiles. Will test more these days and see.
