lovettchris commented 3 years ago

.NET Core Version: 5.0.302
Windows version: 21G2 build 22000.100
Does the bug reproduce also in WPF for .NET Framework 4.8?: Yes
Is this bug related specifically to tooling in Visual Studio (e.g. XAML Designer, Code editing, etc...)? No

Problem description: Copy / paste an image from mspaint.exe doesn't work, it used to work.

Actual behavior: No images shows up in the element. But I CAN load the same image from a file on disk.

Expected behavior: This should work and used to work:
```
BackgroundImage.Source = Clipboard.GetImage();
```
Minimal repro:
1. unzip attached repo
2. run ~\WpfPasteBug\WpfPasteBug\bin\Debug\net5.0-windows\WpfPasteBug.exe
3. open the ~\WpfPasteBug\untitled.png in mspaint.exe
4. Select all copy and paste the image from mspaint into WpfPasteBug.exe using CTRL+V
5. Nothing shows up.

I honestly don't think this bug is new with Windows 11. This is an issue we also ran into, and worked around by falling back to the WinForms Clipboard API. And we seem to not be the only ones with that experience.

Ah, ok, I agree I am able to repro the bug on windows 10 also.
