Description of the warning/error

I am not sure if you can address this, but I am seeing this message after test suite has finished. I notice it only appears in the output if the robot command is run through a bat file. Does not appear if I call robot through terminal.
Similar issue was opened on opencv and marked as 'wontfix' without explanation. - opencv/opencv#8919

The message comes from opencv but it doesn't affect the functionality of the library. There is nothing that can be done in ScreenCapLibrary side at the moment.
