By default, scrcpy automatically synchronizes the computer clipboard to the device clipboard before injecting Ctrl+v, and the device clipboard to the computer clipboard whenever it changes. This new option --no-clipboard-autosync disables this automatic synchronization. Fixes #2228 <https://github.com/Genymobile/scrcpy/issues/2228> PR #2817 <https://github.com/Genymobile/scrcpy/pull/2817>
