OCR plugin only shows black screen

[monotron-blue]

I've been having an issue with the plugin, it was successfully installed or recognized but when I try to use the OCR, the OCR window only show a black screen and nothing happens no matter how much time I give it, only when I click the window a vertical typing bar (Insertion point cursor) appears and then nothing happens.

I reinstalled Ksnip and plugin several times, same exact behavior.

The specifications for the ksnip and ksnip pluing ocr are the following:
