Firefox screen rendering

[Ventero]

Firefox has long had problems with rendering images on the move. Compared to other browsers, the image is jerky and slightly blurry in motion.
This is especially noticeable when running subtitles, watching hockey, or any scene where there is more sustained motion.
The problem is probably at a level somewhere around HW-acceleration and vertical sync.
I want to report this to the developers and ask for improvements - the video is not easy to watch via FF.

I'm posting a link to a test video in Full HD, using the 15:17-15:31 minute segment. For example in Edge or Chrome it runs fine - on FF the movement is noticeably choppy and jerky.

If I'm out of line here, please advise me how to inform the developers about this. I don't want to lose Firefox - it's my favourite browser, but this way I have to use 2 unnecessarily.
Thank you.

This problem applies to both Linux and Windows - the correct GK drivers are of course.

The dev-webdriver mailing list is specifically about the WebDriver implementation in Firefox, but your problem seems to be a general issue with Firefox.

I suggest to either file a bug (eg in Core : Audio/Video at https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=Audio%2FVideo), or describe your issue in the public chatroom for Firefox desktop (https://chat.mozilla.org/#/room/#fx-desktop-community:mozilla.org) ?
