SW2019: drawing is slow

hello,

the drawing is bit impossible to manage... it recalculate everytime I make a zoom, move on screen, if I delete a quote, annotation, ax, centerline, it "think" for many time (such for some minute) 

Is there many option which help me? for example: something that delay any update?

many thanks

ciao a tutti
