Hi again fl0rm :)
Good to hear.
I now see the issue. 'Desktop' mode does not currently allow to use the automatic mode. The reason for that is that I could not find a solution where it was possible to take a screenshot of the monitor without including the GameTranslate window in the screenshot as well. Which led to the just before captured/translated text being the text that was read in the next poll.. There are solutions to this, but none that could work with how our current window is created and used (afaik).
I believe the 'Desktop' button should have a tooltip that lets the user know the automatic capture mode is disabled. Let me know if you can't see it! :)
Have you had any success playing your game with 'Attached' mode? It should work just fine for your use case. Also make sure that you use the 'AutomaticWindow' keybinding, the 'FastKey' and other hotkeys do not work for that.
Diffing strings or similar solutions could very well be a good enough workaround, but that would still require the text to constantly be OCR'd. I think I have a better solution in mind that only involves taking a screenshot and calculating if an update should be done or not, but I am yet to have time to put that into practice.
Thank you!
