I am also experiencing similar issues with video stuttering and Google
Meet which completely freezes after a while. I am not on lunar lake.
Comparing the GPU field in `about:support` in the firefox snap from
latest/stable and the deb shows the following:

firefox snap from latest/stable:

GPU Description: RENOIR (renoir, LLVM 15.0.7, DRM 3.61, 6.14.0-32-generic)
...
Driver Vendor: mesa/radeonsi
Driver Version: 23.2.1.0

firefox deb:

GPU Description: AMD Radeon Graphics (radeonsi, renoir, ACO, DRM 3.61, 6.14.0-32-generic)
...
Driver Vendor: mesa/radeonsi
Driver Version: 25.0.7.0

Using the firefox from stable/core24 results in my GPU description to
show "AMD Radeon Graphics" but the firefox version in that channel is an
older one so I don't think that is really a solution.
