+[](preview-all-windows.png)
+I used two X11 extensions — XComposite's off-screen storage feature
+and XRender — to capture the window image.
> [!WARNING]
-> If you're using patches for fullscreen and hidewin, please follow the comments in my patches and adjust the code to suit the effects of other patches
-
-> The project is still in the development stage, and there are still many problems, such as: without using a renderer like picom, the window image will not be available, but fortunately there is no crash
+> The project is still in development.
-> (I'm sorry because I've been using picom and this issue didn't come to me until I was making diff)
+> If you're using patches like `actualfullscreen` or `awesomebar`, please uncomment
+> the corresponding one in `config.def.h`.
