GNOME 45.5 Is Here with Small Updates for GNOME Shell, Mutter, and GNOME Tweaks
Coming a month after the GNOME 45.4 release, GNOME 45.5 is a small update that removes the experimental rt-scheduler feature from the Mutter window and composite manager because there’s now a dedicated KMS thread that also has real-time scheduling capabilities.
It also fixes the automatic closing of FreeDesktop.org notifications, as well as a regression causing keys to get stuck when raising the lock screen shield in GNOME Shell. Moreover, GNOME Shell 45.5 adds explicit use of /bin/bash rather than /bin/sh, which should prevent some issues on Ubuntu 22.04 LTS or similar systems.
