I guys, I have this strange issue. When playing, if i like alt-tab to go search something on the browser, when i go back into the game, this is freezed into the last frame I were but i can still hear the sound of the game, as if it's some kind of video problem. Some of you had the same issue? how can it be fixed?

btw I use the Rise of the White Wolf mod, i dont know if that could be the issue or not.

Lots of older games don't like it when you alt+tab out of them, The Witcher may be one of them.
