[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)

该 issue 涉及 Onscripter 的屏幕缓冲区叠加导致的文本重影问题。在 C# 项目中查找处理文本渲染和屏幕缓冲区管理的代码，特别是在第 3 集中召唤 Chiester 姐妹的场景附近。检查是否存在与文本显示或视觉效果相关的现有测试。使用提供的截图和视频链接重现该错误，以确认文本重影行为。
