start up screen flashing black and white
when i open adobe illustrator the screen flashes black and white continuously and the menus close instantly when i click on them. i can open a new document by pressing ctrl n but cannot click on any of the menus.
this only happens when i am signed in, which i need. i can sign out by quickly clicking the sign out button in the help menu before it closes again, but this is not ideal.
this only happens in illustrator CC 2015, not photoshop.
