User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/112.0.0.0 Safari/537.36

Steps to reproduce:

1. Launch Firefox (snap) on Ubuntu 22.04
2. Visit earth.google.com
3. Interact with the Google Earth application

FYI, here is the snap info firefox on my installation:

  installed: 112.0-2 (2559) 253MB -

Actual results:

Note that interacting with the app results in massive CPU spikes and low FPS (~5fps)

Expected results:

CPU should have remained low (<10% CPU utilization in non-snap Firefox)
FPS should be visibly smoother/modern

FYI necessary factory Radeon drivers are present:

root@themachine:~# ls /usr/lib/x86_64-linux-gnu/dri
crocus_dri.so i915_dri.so kms_swrast_dri.so r200_dri.so radeon_dri.so virtio_gpu_dri.so
d3d12_dri.so i965_dri.so nouveau_dri.so r300_dri.so radeonsi_dri.so vmwgfx_dri.so
i830_dri.so iris_dri.so nouveau_vieux_dri.so r600_dri.so swrast_dri.so zink_dri.so

Non-snap Firefox does not exhibit the same behavior on same machine / OS install

Non-snap Firefox does not exhibit the same behavior on same machine / OS install

Please also attach about:support of that non-snap Firefox. Thanks!

Juan, could you share about:support from non snap? Also, can you give a test to MOZ_ENABLE_WAYLAND=1 firefox to check if Xwayland / Wayland has a play? Upstream issue linked might be a dupe.

And by any chance, can you test core22 base? I think you need snap refresh --channel=candidate/core22 firefox

Comment 8

[:gerard-majax]

This might have evolved a lot since the switch to core22, can we get an update ? Otherwise we should consider RESOLVED:WORKSFORME

Comment 9

[BugBot [:suhaib / :marco/ :calixte]]

Redirect a needinfo that is pending on an inactive user to the triage owner.
:gerard-majax, since the bug has recent activity, could you please find another way to get the information or close the bug as INCOMPLETE if it is not actionable?

For more information, please visit BugBot documentation.

Based on lack of other reports and that my AMD hardware properly reports GPU now on core22 and Google Earth is smooth and GPU properly reported, I'm going to close as WORKSFORME. Please file a new bug if you experience this with about:support, snap info firefox as well as snap connections firefox at least.
