@MartinZikmund This looks like the same issue I was facing that I was going to open an issue for today :)

Image rendering will start using different APIs to ease support for Gifs starting with #15951. So we should first evaluate if #15951 will have any impact, and build a fix on top of that.

The issue is visible on the TubePlayer Sample app (Single Project) as well for .jpg images that are not transparent
Sample for repro: TubePlayer.zip - Uno.Sdk: 5.2.108 | (Details for the Youtube API Key for appsettings.development.json if needed)

@Youssef1313 I can reproduce the issue as well on the TubePlayer Sample app (non-Single Project) using previous 5.1 version. Sample for repro TubePlayer.zip - Uno.WinUI: 5.1.87
