Translated text displayed as blank

Hi,
When I tried the OCR translation, after using it repeatedly in a game, eventually the translation starts to only show blank and no translation:

Ok so after I clicked this window the translated text now appears. Seems like if this window is out of focus, the text hides itself.

Thank you for the feedback, I think I need to check the text color
