我正在尝试构建这个程序：https://github.com/elkowar/eww \n但是我没有任何 Rust 知识，我想知道是否有人可以向我解释该构建错误的含义。我安装了 Rust 的 Nightly 版本。

以下是构建错误消息：

我想知道我的 picom 配置文件出了什么问题。我目前使用 Arch Linux - 5.6.10 和 i3-gaps 作为 WM，使用 Picom 作为合成器。

错误信息：

[ 08/05/20 13:43:36.014 init_render WARN ] Old backends only support blur method "kernel". Your blur setting will not be applied

有人可以告诉我这是什么意思吗？
