not really a time lag but more just a distance thing? if I zoom in, it gets better since, well, it's zoomed in. Also, one thing I noticed is that if I end up working on a layer for a long long time and have tons of details on it, flipanim will get super laggy for things like adding a new frame, undoing and redoing, etc. But if you start a new frame which is completely fresh instead of copying a previous frame, the lag is entirely gone. I have a feeling it's something to do with the memory of all the lines you've made, and how far you can undo and all that. It's not really a problem because I only encountered it after doing like... 140 frames without starting a new 'scene'. My first animation was I think 200 frames? the "origin" one
