Public bug reported:
a last-hour upload of mutter for kinetic release fails to build from
source on armhf due to what appears to be a regression in mesa's
llvmpipe implementation in the mesa 22.2.1-1ubuntu1 build.
If this is a regression in mesa, it should have been possible to detect
it before mesa was promoted, via autopkgtests in the mutter package.
Counterintuitively, mutter declares autopkgtests, but the autopkgtests
do NOT test any of the OpenGL functionality via the mutter "nested
view". Therefore the regression was only detected at the next upload of
mutter, NOT before mesa was promoted to the release, when we want to be
catching it.
Please fix mutter to ensure that the autopkgtests have at least as much
coverage as the build-time tests, which is the right way around.
