Autohotkey: v1? , v1_H ?, v2?

[ScottMeyer]

Hello,
I am doing a program that needs to display 1000 objects in a resizable window.

I use Autohotkey 1.1.26 (basic), I tested my script on "Autohotkey v1H" and I see lag and display bug.

I wonder, for reasons of performance:

What do you recommend ? use Autohotkey: v1? , v1_H ?, v2?

If you have asked yourself the question, thank you for your answer.

cordially

Can you post an example of 'lag and display bug'?

EIDT:
If you don't need andy of these features , there is no need to switch to AHK_H.
