When typing anything on any GUI ingame, if you hover the mouse on anything in the world, structure, resource, robot, fish, anything, the screen flashes for a tick and resets its behavior to default position, if we're typing, say, a station name and a robot drives below the arrow, the name gets reset as the GUI resets its position and contents, if we're editing a blueprint and the same joe robot passes under the mouse pointer, it'll make you lose all the changes you did to the blueprint.
