User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:132.0) Gecko/20100101 Firefox/132.0

Steps to reproduce:

I tried Ubuntu 24.10 with Wayland on my PC which includes a Nvidia RTX 2080 GPU.
My nvidia driver is the latest available directly from Ubuntu : 560.35.03 (nvidia-driver-560-open)

Actual results:

Scrolling in web pages is janky with a lot of stutters.
Seeing videos on Youtube leads to a lot of CPU usage.

When I look at about:support, I see that Firefox is not using my GPU to render web pages. I see "Webrender (Software)" and "Mesa -- llvmpipe (LLVM 15.0.7, 256 bits)" in WebGL driver.

Expected results:

Smooth renderer of webpages.
Reduced CPU usage with GPU rendering, like on the X11 session.

Contrary to what I said on my initial comment, Firefox is not using my GPU in the X11 either.
I have software renderer in about:support too.

OS: Unspecified → Linux
Hardware: Unspecified → Desktop

And to be absolutely clear, the Firefox flatpak from Flathub has not this issue.

The flatpak about:support mentions X11, is comment 5 correct ? Is this a regression ? Do you reproduce on edge channel ?
