SUMMARY
system slowly becomes unresponsive, applications wont redraw updates, clicking on another window or app forces a redraw. Changing any of the settings in display and monitor > compositor provides a temp fix before it will eventually fully freeze up.


STEPS TO REPRODUCE
1. 
2. 
3. 

OBSERVED RESULT

Any open app will eventually fail to redraw and be stuck. Notifications will popup as black boxes, any tool tips or menu options also show up as black boxes. Then bottom task bar will become frozen. Followed by the display freezing up completely and the mouse cursor is the only thing I can move.
