After pressing Ctrl+C to copy to clipboard, or Ctrl+V to paste, the app where I pressed the shortcut hangs for several seconds. I've observed Ctrl+C hang inside the machine I remoted into, and Ctrl+V hang in the physical machine I'm on.
I've observed that both on macOS and Windows (10 and 11). The target machine is always Windows 11, and I'm remoting into DevBox (devbox.microsoft.com). On Mac I also have Parallels Toolbox with Clipboard History, not sure if that matters. The target machine is almost always plain vanilla DevBox with little to no modifications.
The hang happens when the app calls into the OS Clipboard APIs. Usually 2-3 seconds, but sometimes up to 5-10 seconds??
