Any equivalent in Avalonia of good old WPF AddDirtyRect ?

[LaurentInSeattle]

Context:

App is updating a writable bitmap given as the source of an Image UI object.
When the WB gets updated, the image is not updated unless InvalidateVisual is invoked.
No need for a layout update, just a redraw is needed. WPF would do that with AddDirtyRect.

Q:
Do we have any better solution than invoking InvalidateVisual ?

Thanks!

InvalidateVisual doesn't invoke layout update:

Avalonia/src/Avalonia.Base/Visual.cs

Lines 377 to 380 in 3c317f5

	public void InvalidateVisual()
	{
	VisualRoot?.Renderer.AddDirty(this);
	}

You might be confusing it with InvalidateMeasure.

My bad, yes, confused by old WPF InvalidateVisual which was calling InvalidateArrange()

Thanks for the quick response.
