As you see in the gif, I placed so much items in these tracks. Then I try to do these in cycle:
Code:
paste
undo
paste
undo
......
And you see when I press undo, the four items disappeared one by one, just like a slow motion of undo. And when I delete all those items, the undo become fast again. And if try
Code:
delete
undo
delete
undo
......
They appeared one by one
So is that when you place too many items in project, it will be slowed down?
