gnome-shell 1:3.32.2+11+g1c6abf378-1

downgrading to 1:3.32.2+6+g8b9874089-1 fixes the problem

issue confirmed, same problem, same resolution. That's a blocker, it renders the whole desktop environment completely unusable, possibly causing headaches for many newcomers :|

I disagree strongly with "Severity: Low". This renders the whole system useless, even GDM refused to start.

I’m using a custom mutter package (based on 3.32.2). Unfortunately the current extra/mutter PKGBUILD doesn’t build so i cannot update it:
fatal: bad object a2507cd51a248e2ee50eb64479f47e5da2564535

From a repo perspective i can understand that the combination of random git packages is working, but it’s definitely annoying when you try to work with it outside of that.
It would definitely help if the package specified that it relied on a specific (git) version of another package.
Also, i’m not sure i like that some patches are applied here that are not only regression/severe bug fixes.

I kinda expect to get upstream version of software. (official Arch philosophy could be argued here)

With all that, i’m not even sure updating mutter would fix the issue now, just figured from the correlating changes…

I suspect that the package `mutter-topicons-cpu-use-fix` was causing the problem. Once replacing this one with `extra/mutter`, I no longer have issues with gnome-shell 1:3.32.2+11+g1c6abf378-1.

So just to be clear, the problem only manifests when using a custom mutter package?

The solution seems clear: your custom mutter package must use the same git commit as the [extra] package.

(And no, I don't happen to agree with packaging non-release commits for software, you will notice that that is only common in the gnome desktop stack, but I'm sure the gnome ecosystem maintainer has his reasons, so there is nothing to be done here unless the actual repository packages are broken.)

Please open a separate bug report about this. Packages which no longer build from source are definitely problems.
