Reproduce the issue on Linux using the supplied Flutter example and the Pasteboard.writeImage and Pasteboard.image APIs. Inspect the pasteboard implementation behind those entry points to determine why the image round trip returns null. Done means writing the supplied image and reading it back returns non-null bytes.
