Hi Tung,
Thanks for your feedback in this community. I have go through the video you shared, and notice the lag you described.
Normally, when you open your Office products and go to Insert Tab > Insert Shape, it will need to load the shape objects, and the second time you click on it, it should be appear in a flash as the objects have been loaded already. So the delay is expected and the lagging time is different depending on your PC's hardware.
We do understand this behavior has caused you so much inconvenience and feel sorry about it. If you still have a strong concern on this, we would suggest you follow the link below to submit your feedback directly to the related team:
