As far as I can see, it happens regardless of Windows version when desktop composition is enabled (if SC is allowed to disable composition, the picture appears immediately; since composition cannot be disabled on Windows 8 and up, the problem is always visible with these versions, but when [WALLPAPER] is used, the problem can be reproduced on Vista and 7). Repeater doesn't have any effect on the problem.
I also noticed that the tray icon (on server) doesn't respond while the client is waiting for the picture to appear.
