Package: mutter-common Version: 48.7-0+deb13u1 Severity: normal Tags: upstream X-Debbugs-Cc: [email protected]
After upgrading from Debian 13.2 to 13.3, the transition from GDM to the GNOME session shows a momentary black screen (flash) instead of the smooth animation that existed before. * What led up to the situation? Upgraded from Debian 13.2 to 13.3 (released January 10th, 2026) which includes mutter and gnome-shell "bugfix releases". * What exactly did you do (or not do) that was effective (or ineffective)? Simply logged in via GDM after the upgrade. * What was the outcome of this action? Screen goes black for a moment, then the GNOME session appears abruptly. * What outcome did you expect instead? Smooth animated transition from GDM greeter to the desktop session, as it worked in Debian 13.2.
