void setup(){
  size(200,200);
}

void draw() {
  background(255);
  rect(10,10,180,180);
}

with breakpoint on "rect" line and using either Continue or Step

Environment

Now fixed for 4.0 beta 2, thanks for the report.

The issue was that not everything was getting set up properly if you selected the option from the menu, but it was working fine if you used the toolbar button.
