Glyphs freezes for 1 second when moving around the artboard

Glyphs

I’m having Version 2.6.3 (1271)
The problem is that it freezes for 1 second every time I try to move around the artboard by holding space & drag around.
Anyone has the same problem and is there any way to fix this?

What MacOS do you have?
How many glyphs do you have in your edit view?
Can you check the macro panel and the console.app?
Can you start Glyphs with the Option and Shift key pressed.
