Thanks for the report.  I cannot reproduce using a VM like:

$(./pre-inst-env guix system vm gnu/system/examples/desktop.tmpl) -m 4g

Did you try rebooting?  This would clear the GDM state files, kept on a
tmpfs.

I don't have a clear idea.  Mutter was recently updated but that doesn't
seem to cause a regression, as shown above.
