BST: Snap Area overlay remains on screen after drag/drop

When I drag an app to the snap area, sometimes the animation repeats several times / flickers, the app will resize correctly however all snap area overlays remain on the screen. I have to restart BST to get rid of the overlaps from my screens.

It only happens randomly (several times a week) - and as far as I can tell it happens to different apps.

This is happening on Ventura 13.4.1 & BST 1.9.9
