apport information ** Tags added: apport-collected wily
** Description changed: On recent update from 15.04 to 15.10, the new 4.2 kernel is associated with graphics instability after a few seconds of GUI use with mouse and keyboard making the GUI unusable. See another person's same experience with intel graphics here: askubuntu.com/questions/688649/kubuntu-wily-upgrade-screen-glitch Downgrading to the last 15.04 kernel solves my issue.
