Weird overlay glitch!

Hii, I have had this annoying glitch for a while now and I can’t seem to get rid of it. As u can see in the picture below, there is a weird outline around the mouth overlay. And then the overlays also flash when fading in and out. Does anyone know how to fix the two issues??

With the overlay flashing, I had this too. There’s a simple fix though!
When you create the overlay, make sure you use & instead of @. I usually do this:

@overlay OVERLAYNAME create
&overlay OVERLAYNAME shifts to xyz
&overlay OVERLAYNAME scales to xyz
&overlay OVERLAYNAME moves to layer xyz
@overlay OVERLAYNAME opacity x in s

This should stop the flashing ^^ or you could always do it with all &, it doesn’t make difference.
I’m not sure about the outlines, though. Maybe if you go to navigation, then press hide debug elements of HUD then they might go away. This is what the normal reader will see when they read your story.
