Compositing/Semitransparency of Plasma/Kwin broken using llvmpipe on

Bug description:
Version: 24.2.2-1ubuntu1
Release: oracular 24.10
After upgrade to mesa 24.2.2-1ubuntu1 in oracular,
compositing/semitransparency of Plasma/Kwin broken using llvmpipe on
x11. Very noticeable on Plasma widgets/panels.
This is particularly prominent for testers trying our live ISO session
(is still X11 for compatibility) in VMs such as Virtualbox/qmemu/etc
with no acceleration. With the 24.10 beta coming in less than a weeks
time, this is bad timing.
EDIT: Also as a result of this issue, the try/install screen on the
live ISO session is wrongly tinted orange. This occurs under the same
conditions as the transparency issue.
An issue has been opened upstream by a user/developer on Mandriva with
the same issue.

Screen shots can be seen there of the impact. I have commented and
added screenshots from Kubuntu 24.10.
