+mutter (48.4-1) experimental; urgency=medium
+
+ [ Jeremy Bícha ]
+ * New upstream bugfix release
+ - Unlink outputs from unused connectors in update_outputs, avoiding a
+ use-after-free when a monitor is disconnected
+ (mutter!4474 upstream)
+ - Fix a crash caused by a use-after-free when clearing many
+ accumulated notifications
+ (mutter#3970 upstream, LP: #2102063)
+ - Fix a non-reproducible crash caused by a use-after-free when dragging
+ an epiphany-browser tab to create a new window
+ (mutter#4157 upstream)
+ - Fix the logic for when to disable the --no-x11 option
+ (mutter!4485 upstream, not relevant to how we configure it in Debian)
+ - Rate-limit visual alerts to 2 per second, to comply with the European
+ Accessibility Act and avoid potentially triggering photosensitive
+ seizures
+ (mutter!4487 upstream)
+ - Fix a rare crash with a NULL pointer dereference
+ (mutter#4147 upstream, LP: #2100243)
+ - Avoid reopening an inactive Nvidia GPU when not needed
+ (mutter#3550 upstream)
+ - Fix a NULL dereference in the tests
+ (mutter!4495 upstream)
+ - Fix stacking order for windows that get activated before mapped
+ (mutter!4462 upstream)
+ - Fix incorrect cursor over Xwayland clients
+ (mutter#4033 upstream, LP: #2111502)
+ - Improve Wayland spec compliance by sending Wayland seat name before
+ its capabilities
+ (mutter#4119 upstream)
+ - Improve X11 compatibility (especially in Wine) by moving the X11 focus
+ to a shared dummy window when the Wayland focus is really on any
+ non-X11 window
+ (mutter!4447 upstream)
+ - Wait longer for hotplugged monitors to detect their input sources,
+ improving compatibility with e.g. MSI PRO MP275Q
+ (mutter!4442 upstream)
+ - Make sure the cursor is updated after modesetting, even if there is no
+ application window to redraw
+ (mutter!4452 upstream)
+ - Fix high resolution scroll events getting converted to discrete events
+ that intermittently switch direction
+ (mutter#4128 upstream)
+ - Documentation updates
+
