Another examples of the screen refresh problem on the Mac?

I suspect this is a problem peculiar to the Mac.

When I run:

   set the lockmoves to true
   move grc "Oval" to tPoints without waiting 
   move grc "rectangle" to tNewPoints without waiting 
   set the lockmoves to false

The oval moves reasonably smoothly, but the rectangle take several abrupt steps.

Is this another manifestation of the screen refresh problem on the Mac? Normally I intersperse a "unlock screen" command to force a screen refresh, but I can't do that with the "move" command.
