Title:
  GPU acceleration via VirGL is broken in qemu

Status in Release Notes for Ubuntu:
  New
Status in mesa package in Ubuntu:
  Fix Released
Status in mesa source package in Mantic:
  Fix Committed
Status in mesa source package in Noble:
  Fix Released

Bug description:
  
  [ Impact ] 
   * Enabling GPU acceleration can cause host-side crashes on mantic/noble VMs 

   * This was reported by someone else upstream and is already fixed by 
     https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25580.

  [ Test Plan ]

   * I've tested the patch on an affected macOS host running Ubuntu in UTM with 
     OpenGL enabled on both Mantic and Noble VMs.

   * Anyone else can do the same on an affected host by simply installing the 
     patched package and booting to the desktop.

  [ Where problems could occur ]

   * This patch fixes an upstream mesa regression which caused libvirglrendrer 
to 
     crash on the host side.

   * This makes a non-working use case work, VirGL on affected hosts cannot 
     regress as it simply didn't work before.

   * Risk of breakage is mainly from other packages possible affected by a mesa 
     rebuild.
