 Rendering engine to draw your UI on a Skia canvas, with gestures and animations, designed to draw pixel-perfect custom controls instead of using native ones, powered by [SkiaSharp](https://github.com/mono/SkiaSharp)😍. 
 Create and render your custom controls on a hardware-accelerated Skia canvas, with effects and animations.
 
+**IMPORTANT UPDATE**
+Reverted SkiaSharp from 2.88.9 to 2.88.9-preview.2.2 
+until [scaling issue](https://github.com/taublast/DrawnUi.Maui/issues/130) is solved for Windows 
+
 Supports **iOS**, **MacCatalyst**, **Android**, **Windows**.
 
 * To use inside a usual MAUI app, consume drawn controls here and there inside `Canvas` views.
