Trying to identify the source of a bug that is making drafting very difficult

[jay@sitetechnologies.io]

I am using AutoCAD 2021.  I do have several .LSP files that have recently been added to my startup, so I'm curious if that could be a cause of a bug I am experiencing. 
I just started experiencing the bug shown in the GIF below.  It is as if the lower third of the CAD view "skips", my mouse cursor jumps over it.  You see in the GIF that it jumps from the drafting space into the command line.  I have restarted the application, my computer, switched mice, and it persists.  If this is not the correct forum for this question, I will remove, but you all are so helpful.

doubt lisp file can cause this but easy enough to check , disable / remove all from autoload and then turn back on one by one. My first thought would be graphics driver. Maybe this article can help you :  https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Cursor-is-slow-or-jerky-in-AutoCAD.html
