The "error" was not obvious, you'd have to sit in range and in front of the dummy and in combat for a LONG time to start noticing a subtle screen jerkiness at first, gradually getting worse. And every time you made a change to the code, you'd need to start all over again (due to the /reload).

To trace it I added a short exit in various places (10 places), controlled by a runtime flag, which I could set using slash commands without reloading the addon. I let it run until I noticed the screen jerkiness (made coffee, boiled the kettle, cut the grass etc) and once the jerkiness was unmistakable then I started modifying this flag to cause a short circuit exit and eventually I hit the point where the jerkiness disappeared or re-appeared, and that was around the CreateFrame. That's how I got the culprit.
