[Bug 2080620] Re: Compositing/Semitransparency of Plasma/Kwin broken using llvmpipe on x11 since 24.2.2

[Rik Mills]

** Summary changed:

- Semitransparency of Plasma panel/widgets broken using llvmpipe on x11 since 24.2.2
+ Compositing/Semitransparency of Plasma/Kwin broken using llvmpipe on x11 since 24.2.2

** Changed in: mesa (Ubuntu)
   Importance: Undecided => Critical

** Description changed:

  Version: 24.2.2-1ubuntu1
  Release: oracular 24.10
  
- After upgrade to mesa 24.2.2-1ubuntu1 in oracular, semitransparency of
- Plasma panel/widgets broken using llvmpipe on x11.
+ 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.
