All windows share one WM_CLASS

• All the windows created by FreeRDP have the same WM_CLASS property. If I open Visual Studio, MSPaint, then PowerShell, all the windows will have the WM_CLASS(STRING) = "RAIL", "Microsoft Powershell" properties (very likely a FeeRDP limitation). edit: https://github.com/FreeRDP/FreeRDP/issues/6570#issuecomment-725878476

• I have graphical glitches when opening winapps programs / rearranging the screen layout

Then I can see the windows decorations in other workspaces:

• Context menus (right-click) are often a black rectangle in various programs (like the Windows Explorer)
