Ok now this is interesting. There is no noticeable difference between 100% and 500% zoom. Hardware acceleration was enabled so I figured I disable it and see what happens. For the same annotations shown in the video, having GPU rendering disabled is way more performant. There is no stuttering and all strokes move together (no lag between strokes). However, when moving a larger selection (e.g. 8 bars instead of the 1 shown in the video) the editor basically freezes up when nudging, making it unusable. I've also played around with Windows' power plans and rendering settings, to no avail unfortunately. 

I'm a software dev as well so if I can do something else to help debugging let me know.
