problem 问题

I googled the problem and got the suggestion to change the Parent of the picturebox, which i tried, but this happened: 我用谷歌搜索了问题并得到了改变图片框的父母的建议，我试过了，但这发生了：

it works, but only in the log's picturebox area 它有效，但仅在日志的图片框区域中

I'm clearly doing something wrong. 我显然做错了什么。 Can somebody help? 有人可以帮忙吗？

WinForms does not support true alpha-transparency. WinForms不支持真正的Alpha透明度。 "Transparent" controls re-render only the parent form's background behind themselves - controls cannot be truely layered and blended in the Z-axis. “透明”控件仅重新渲染父窗体背后的背景 - 控件无法在Z轴上真正分层和混合。

So what you're after really isn't possible. 所以你真正想要的是不可能的。

However, implementing a game using WinForms controls and GDI ( System.Drawing ) is a bad idea - performance is terrible (in part due to Microsoft's crippling of GDI since Windows Vista by removing hardware acceleration of many operations) and there are endless issues with inconsistent double-buffering and DPI-scaling. 然而，使用WinForms控件和GDI（ System.Drawing ）实现游戏是一个坏主意 - 性能非常糟糕（部分原因是微软自Windows Vista以来通过删除许多操作的硬件加速而导致GDI严重崩溃）并且存在无限的不一致问题双缓冲和DPI缩放。

I suggest you rewrite your game's rendering layer in Unity, Direct2D or SDL. 我建议你在Unity，Direct2D或SDL中重写游戏的渲染层。
