Intermittent Writing While Video Sharing on Whiteboard

Well this is my attempt at writing the letters of the alphabet.  Anytime you video share the pen will not register some strokes.  It's extremely annoying.  Writing on the whiteboard without sharing works fine, every other app works fine, for instance writing in gimp, but as soon as you share video, even the new whiteboard app begins to skip strokes.  My zoom installation at home works fine but my new zoom installation started doing this.

I would upload a video but i'm not allowed so here is a screen shot.
