Why does this program use Graphics Capture API?

This program uses Graphics Capture API on the host computer side.

In a remote desktop connection, the cursor on the host side is normally not displayed. However, the GraphicsCaptureAPI allows the cursor to be displayed, so this program creates a button which can turn this feature on and off and captures that window.

Known issues

  • Windows Defender misidentifies the DLL as a Trojan horse program. (#2)
