I copy and pasted an audio part, the gray part in the screenshot below, and noticed it was progressively getting more and more off the grid as I copied it, so I zoomed as far down as I could on the source clip, and notice at full zoom, its edges are protruding. With or without snap on, I cannot correct this. Grabbing the handle on the part, it either wants to extend beyond the grid marker, or move before it. The cut tool will not cut on the grid line to make it align with the pink and green parts you see in the screenshot, and will only cut either a bit in front of the grid or behind the grid. Snap on or off makes no difference.
Does anyone know why this is happening, and how I can fix it? Thanks!
