Well this does happen with just dropping a circle with a cursor. But i still can save and send something if that could help, let me know.
Looks like the whole software is stuttering, as i can see the fps showing « 4 fps » right after a drop (then goes back up). Another behavior of this bug is it makes the cursor jump and miss triggers. I hope i’m clear with my explanations ^^
I’ll be able to try on another computer in a couple of days to see if its config related.
