How do I keep syl borders from overlapping previous syls?
The syls are likely improperly layered. When on the same layer, ASS events that are not subject to collision detection (e.g. when positioned using ) will be drawn on top of each other in time and source order. That means later syls will be painted on top of earlier syls, and if those syls have borders in the same event as the fills, the borders will also be drawn.

To prevent this issue, ensure that the border and fill are separated into layers similar to how one would separate them for typesetting and ensure that the fill is set to a higher layer than the border.
