this issue occurs on installed systems (my primary d960 which used to be 19.04, now 19.10), plus live systems (19.04 & 19.10, not when initially booted; but when screens adjusted to be one above the other - but issue only occurs one way; if swapped top-bottom both screens have xscreensaver active on them). Adding disco & eaon tag is reason for this comment; still present on today's daily reason I looked.
