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.
