It seems to be constantly trying to display the main screen, failing, and trying again so that if I move my mouse it keeps resetting in the centre of the screen.
Screen does go black, but main screen never appears and occasionally during the "flicker" I can see windows from the Finder.
Had worked up until yesterday. Not aware of any OS updates.
Tried running from the command-line and gor the following message:
