Does anyone know how to enable that? I'm on Nightly so I should have it for some time already, but I'm not sure if it is on by default or should I tweak some value.

  Is this about WebRender? If so, here you go: https://www.omgubuntu.co.uk/2020/07/firefox-enable-webrender-linux https://www.omgubuntu.co.uk/2020/07/firefox-enable-webrender...

  What does "Compositor:" say for you in about:support?
- jdhawk 6y ago
  gfx.webrender.all layers.omtp.enabled layers.acceleration.force-enabled
  - muizelaar 6y ago
    layers.omtp.enabled isn't used when WebRender is on.

      ah, nice - thanks

I'm seeing high CPU usage on YouTube after recent updates on Xubuntu. I think it started when they enabled GPU acceleration by default. Previously I could watch even FHD videos without much fan noise, but after recent updates, fans spin at the max speed by playing even 480p quality vids. Anyone else?

  GPU acceleration is not a magic bullet it seems. In our case drawing large SVGs suddenly becomes really slow when GPU rasterization is enabled. Chrome has the same problem. I really hope we will see more polishing in this area and maybe a cooperation between Chrome and Firefox developers?

    Thing is, when I play the same video with VLC which uses HW decoding, it doesn't even break a sweat. So I think there might be something wrong on the browser part...

      You can issue a bug report on https://bugzilla.mozilla.org/home https://bugzilla.mozilla.org/home Sometimes bugs are fixed really fast, sometimes never. Just give it a try.

      There could be something related to FAN thresholds that resides in BIOS directly thus starting using GPU just slightly over some minimal limit might raise FAN speeds significantly and not be related to temperature raise as there is some inertia between temperature readings and real temperature inside GPU core. I'm also experiencing FAN noise raise on my Ryzen APU based laptop.

      i mostly stopped bothering with in-browser video when mpv wiht youtube-dl integration came around. either drag the url to the player window or use an open-with addon. hardware decoding, no ads, buffering as i please
  - muizelaar 6y ago
    Do you have an example url for this?

Wait... GNOME only?
- tenacious_tuna 6y ago
  Yeah, that seems odd. I wonder if the update doesn't help/involve Weyland people, and if GNOME is an X11 holdout? I haven't been paying enough attention to know.
- amarshall 6y ago
  Perhaps just by default, or a miscommunication. FWIW I’ve had WebRender force enabled on Sway (Wayland i3 clone) since FF 78 or so.
- muizelaar 6y ago
  Yep. We've seen bugs with different window managers so WebRender is only enabled in Gnome in 84 to minimize the risk of breakage. This restriction will be removed in subsequent releases.
  - aosmond 6y ago
    Also, we have it enabled in nightly and beta for many more configurations already :). There are many bugs to fix, but we're working through them. This is the exact same treatment we gave Windows and OSX in previous releases this year.
  - AshamedCaptain 6y ago
    I know the usual rational about users blaming Firefox and yadda yadda but I am rather not convinced this is how things should work in the open desktops. If there are clear bugs in other environments, file them and break them if necessary. The only potential exception I can see is when it's not clear if it's a bug or not..
