This happens in Writer, Spreadsheet and Drawing - and may happen in other elements of Libre Office too.
Intermittently, and unpredictably, the status bar at the bottom of the screen begins to alternate, rapidly, between at least two display formats, and may also, intermittently display the 'blue squares' Saving bar too.
Simultaneously, the mouse and keyboard become inoperative for a while.
