[BUG] SkiaSharp decode the png file be blur

[lindexi]

Description

I load the png image file as FileStream and I decode it by SKBitmap.Decode. And then I use DrawBitmap to draw it.

Code

All the code in: https://github.com/lindexi/lindexi_gd/tree/eb3ac5885becdbcd609b2d9e936ada221e891221/HabicherbalaHallrujemnowaljere

using SkiaSharp;

var fileName = $"output.png";

var skImageInfo = new SKImageInfo(1920, 1080, SKColorType.Bgra8888, SKAlphaType.Opaque, SKColorSpace.CreateSrgb());

using var skImage = SKImage.Create(skImageInfo);

using (SKBitmap skBitmap = SKBitmap.FromImage(skImage))
{
    using (var skCanvas = new SKCanvas(skBitmap))
    {
        skCanvas.Clear(SKColors.White);

        var inputFile = new FileInfo("Test.png");

        using var fileStream1 = inputFile.OpenRead();

        using var resourceBitmap1 = SKBitmap.Decode(fileStream1);

        skCanvas.DrawBitmap(resourceBitmap1, new SKPoint(0, 0));

        skCanvas.Flush();

        using (var skData = skBitmap.Encode(SKEncodedImageFormat.Png, 100))
        {
            var file = new FileInfo(fileName);
            using (var fileStream = file.OpenWrite())
            {
                fileStream.SetLength(0);
                skData.SaveTo(fileStream);
            }
        }
    }
}

Experiencing the same issue with the latest NuGet version. PNGs are messed up.

Platform: Linux (Docker image mcr.microsoft.com/dotnet/aspnet:6.0) Using SkiaSharp.NativeAssets.Linux.NoDependencies package.

I can also reproduce it with the below console app (w/ 2.88.0 SkiaSharp package reference), and I had someone else try it as well with the same result. Worked fine w/ 2.80.3.

Examine the paths after it runs.
