I’m experiencing some kind of lag when dragging around the Grasshopper window in Rhino 8 and after deleting all kinds of objects I’m confident blaming the script editor.

The problem starts to become a hassle with about ten instances of the script editor no matter if the component is using Python or c# and the editor can even be empty and disabled and the solver can be disabled too.

I do not see the problem in Rhino 7.

On my old laptop with Windows 10 the same problem occurs in Rhino 8 and again nothing suspicious in Rhino 7. Hence I don’t think it has to do with my computers.

@martinsiegrist I have done major improvements in Rhino 8.3 RC in regards to Grasshopper component performance. I’d appreicate if you can test again in this verison

Thanks for the information. It might be slightly better but I still see the Grasshopper window move incrementally when dragging and not in a smooth motion.

Okay I’ll test this specifically tomorrow and make sure to resolve any bugs for Rhino 8.3 public release. Here is the YT for reference:

[RH-79189](https://mcneel.myjetbrains.com/youtrack/issue/RH-79189) Grasshopper window drags really slowly when there are many script components placed on the canvas
