Public bug reported:

When I activate the zoom feature, the screen is well magnified but the
mouse pointer stops moving when displacing the mouse. 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.

I can see this error message appearing in the logs :
