why opencv imshow() create a new window has the same name as namedWindow() does in Debug Mode?

Question

I want to create a mat and show it in a window named \"figure\".

If there is nothing wrong, there should be a window named \"figure\", and accept any key to stop.

This problem is due to wrong linking settings.

• In Debug, you need to link only to the debug library opencv_world331d.lib
• In Release, you need to link only to the release library opencv_world331.lib
