[Episode 3] Last line of text ghosted onto screen

I've seen this issue before - the (P)Onscripter has a built in feature which lets you layer stuff into the screen buffer. If you're not careful, you can accidentally draw the game text into the screen buffer too, leading to this problem.

The user posted a video, but this screenshot should be enough to find it.

> (Umineko ep. 3 spoiler) Also this effect behaves a bit weird with the previous line of text faintly showing, and the option button as well if you open the menu. It looks like it's only for those couple of lines so it's just a minor thing.
> It happens right after the Chiester sisters are summoned
> My game setup is the same as in the msg link: (OG sprites with PS3 graphics)

The issue involves Onscripter's screen buffer layering causing text ghosting. Look for code handling text rendering and screen buffer management in the C# project, particularly around the scene where the Chiester sisters are summoned in Episode 3. Check for any existing tests related to text display or visual effects. Reproduce the bug using the provided screenshot and video link to confirm the ghosting behavior.
