Remote Desktop Flashing Issue Due to Screen Capture Engine Switching Desktops in AnyViewer

1. Issue

After establishing a control connection with the remote computer, if you do not operate the remote computer, the remote desktop window will flash for about one minute.

2. Cause

By analyzing the logs, I found that AnyViewer’s screen capture engine was constantly switching desktops. But I don’t know what caused this operation.
