Pointer disappears when 'Activities' is clicked

[themusicgod1]

After logging in, if I click on either the "Activities" or the "date" or the battery/wireless indicator, the pointer visually goes invisible. I can still select things (if the 'invisible pointer' points to them), but the pointer itself is not shown.
When I exit these menus(for example the "Activities" screen) the pointer returns.

Also: when I right-click windows to get the "minimize, unmaximize, ..." menu, the pointer also disappears.

After last update of packages via aptitude this problem seems to have disappeared
