I recently installed windows 10 and now I got a problem. I play Wurm in windowed mode. If I minimize the wurm window and then restore it the game screen is blank white but I can still hear sounds. The only way to fix it is to minimize all windows by clicking in the lower right corner of the windows screen by the clock. Then I can restore the wurm window and continue playing. Another way to restore it is to adjust the size of the window. This wasnt an issue in windows 7. I wonder if anyone else have had this problem and what you did to fix it. I will try a different video driver right now and report results for future reference.
