[BUG] Rendering issue with Rgb888x image

[dbriard]

Description

Hi, I wanted to try Rgb888x format instead of Rgba8888 or Bgra8888, but it do not work as expected.

SKImage.FromBitmap(_bitmap) with Rgba8888 work fine, but SKImage.FromBitmap(_bitmap.Copy(SKColorType.Rgb888x)) give the following result when I DrawImage.

Is it a know but, may be there is a value issue with the enum Rgb888x when converting to image???

Are there any estimated timelines for addressing this issue? We are a vendor of .NET MAUI components (DevExpress), and our PdfViewer control relies on SkiaSharp for image rendering. We've received reports from multiple customers encountering this bug, and it's impacting their experience.

@mattleibow apologies for the ping, but your expertise would be invaluable here. Perhaps you have some information or insights regarding the issue. Thank you!

Converting Rgba8888 to Rgbx8888 produces the same memory layout so all you need to do is a memory copy in combination with some bit operation that sets the last bits of a pixel to 1
