Public bug reported:
When I activate the zoom feature, the screen is well magnified but the mouse
pointer stops moving when displacing the mouse, the display is frozen. A kind
of shadow mouse pointer seems to be moving behind with hover effects on UI
components, but the screen and "real" mouse pointer don't.
When I deactivate the magnifier, the problem disappears.
I can see this error message appearing in the logs when I activate the
magnifier at 20:23 :
before the activation but could be related :
gnome-shell[1755]: clutter_actor_set_name: assertion 'CLUTTER_IS_ACTOR (self)'
failed
fnome-shell[1755]: clutter_actor_set_accessible_name: assertion
'CLUTTER_IS_ACTOR (self)' failed
after :

range for property 'y' of type 'gfloat' (massive amount of log lines)
