app parameter results in black screen

Any idea why the app parameter for RemoteApp result in black screen? Desktop mode works as expected.

Sorry...could you give me more information about "black screen"?

[guy032]

Yes. desktop experience works great but when I try to add this parameter /app:explorer for example or any other app like calc or notepad or full exe path I can see the login screen for a second and after the login I can only see blank (black) screen.
I no longer receive the bitmap events after the login screen when the black screen appears.
Apparently even if I try to test it with wfreerdp: https://cloudbase.it/freerdp-for-windows-nightly-builds/
it still doesn't work with their recent binaries but I can open task manager with keyboard inside the black screen.
the command used: wfreerdp.exe /v:{hostname} /u:{username} /p:{password} /app:calc
Only for Linux with xfreerdp2 I was capable to see this work but not from node-freerdp2.
