My uneducated guess is that this is the source of the incompatibility:
/* 2712D0 (V3D 7.1.10) has included draw index and base vertex,
* shuffling all the fields in the packet. Since the versioning
* framework doesn't handle revision numbers, the XML has a
* different shader state record packet including the new fields
* and we decide at run time which packet we need to emit.

Title:
Mesa bump to 24.2 required for Pi 2712D0 stepping
Status in mesa package in Ubuntu:
Confirmed
Status in mesa source package in Noble:
Confirmed
Bug description:
The Raspberry Pi 5 2GB model now uses the D0 stepping of the 2712 SoC.
Unfortunately, this is only supported from Mesa 24.2.0 (see
https://docs.mesa3d.org/relnotes/24.2.0.html -- search for 2712D0).
The result is corrupted or blank output for the current Ubuntu 24.04.1
Pi desktop (using Mesa 24.0.9). The forthcoming oracular desktop does
work as far as login goes, but snapped applications are still relying
on an older mesa, thus the software center, firefox, and thunderbird
all fail to operate.
Although the D0 is only on the 2GB model *currently*, it is
anticipated to become common to the entire Pi 5 line up going forward,
and will be present on the forthcoming CM5.
Could we investigate either bumping mesa in noble, and the
corresponding content snap, or finding the minimal patch-set necessary
to support the D0 stepping and back-porting that?
