I got a problem with dialog scenes, when the npcs starts talking the screens starts having errors(see picture)

I've tried various compatability settings but it doesn't work, I'm on windows 7

Check your graphics settings in DOSBox. Right now, mine is set to use OpenGL render with Nearest Neighbor x3 filter and I don't have and screen corruption. I don't have the GOG version (I have one of the Forgotten Realms Archives collections), but the render usually defaults to Surface or Overlay in a number of the games.

Its not working :(

You may need to try different renders until you find one your graphics card like. For example I've had success with ddraw and Direct3D in the past (moreso with ddraw).

If all else fails, contact support. They may have some suggestions I'm missing. =)

6 yearsh later... For those looking for answers, try clickin on the printer thingy in the middle of portraits. Then exit the conversation and start it again. Fixed it for me. If you can't see the printer icon, just click where it should be. Bottom middle of the screen.
