A new version will be with the next Testing update. But there is no garantee it will fix anything. As these packages are just built againt the master git repo of Mesa, each Sunday.
Where will the mesa-20.3-rc1 version show up in the repo? Is it basically the same as the git version from this last Sunday?
It won’t. We don’t do RC releases. We have the regular release and then the mesa-git package.
The package from last sunday, will get into Testing branch with the next Testing update.
