Is it possible to use RenderTargetBitmap with the Window hidden?

[treviasxk]

Hello, I need to capture the window's content in the backend using RenderTargetBitmap, but the content isn't fully rendered even when I use InvalidateVisual(), Measure(), and Arrange(). Nothing happens when the window is Hide(), only when it's visible.

I really need to capture it in the backend without using Show() and Hide(), because that would consume a lot of resources for each initialization.

Problem solved, the Headless package disables the window and keeps the rendering as a backend.

public static AppBuilder BuildAvaloniaApp() => AppBuilder.Configure<TestApplication>()
    .UseSkia() // enable Skia renderer
    .UseHeadless(new AvaloniaHeadlessPlatformOptions
    {
        UseHeadlessDrawing = false // disable headless drawing
    });
