Hi, I did a video for showing you what is this "lag" :

It's not realy visible but you can see the "freeze" on the video (it's like jumping or something like that). I don't realy know how to explain my problem but i think the video is enough to understand. Tthanks you for your help and sorry if i did some fault (my english is pretty bad)

This is my exact issue! I'm making a post of my own but have you found a solution?
