Videos lag/stutter when viewing them

[Dr. Leon Sisk]

This is not game related, but when using a browser/in desktop mode.

When browsing on Firefox, videos for some reason will stutter. They seem choppy, and if playback is moved, audio will continue but the video itself won't move until a few seconds afterwards or till going back in the video a few seconds instead.

This problem wasn't a thing before SteamOS 3.3 when the change to Firefox being changed to being installed as a flatpak instead and started after SteamOS 3.3 landed.

I did uninstall and reinstall firefox and no, it did not solve the issue.

Hey, this issue has been annoying me to no end, but I did find that disabling hardware acceleration in Firefox settings reduces the problem (Settings > general > performance > uncheck box). It still happens, but it's less annoying.

It seems like a problem with frame pacing, but I have no clue what could be causing this, and I'm way too rusty with how Linux works to figure it out.

In SteamOS 3.4 Preview, hardware acceleration has been removed in the video driver along with the updated driver causing various weird issues throughout SteamOS, one of which might be this video playback issue
Here is a discussion with links to a few other related issues and my workaround for it, which works by installing SteamOS 3.3's video driver on 3.4.
https://steamcommunity.com/app/1675200/discussions/0/3541546590709961979/
For me video playback of mostly 1080p YouTube is smooth in Desktop Mode after applying the workaround, but I have not tested the unmodified driver in this way.
While I watch a lot of YouTube in fullscreen on my Deck, I use the LibreWolf browser configured to my liking, which is a Firefox fork with the uBlock Origin plugin pre-installed, so differences might arise there too.

P.S. Another known issue is audio stuttering in Desktop Mode, I don't recall where but I have seen a post from a Valve employee stating that this is diagnosed and will be fixed in a future update.

[Dr. Leon Sisk]

Issue's still ongoing sadly.

Can you tell a bit more details please ?

Factory reset my steam deck and can confirm that it didn't fix it. Just figured i'd add this to this old discussion.

Hardware acceleration is ♥♥♥♥♥♥ to get working on Linux. Every moving part is an opportunity to break it.

Did you attempt to touch flatpak to resolve the issue?
