There is a problem that multiple people who play Wurm Online are having. We all run windows 10 and use AMD Radeon 22.214.171.124. When the window is minimized and then restored the screen comes back blank and you must force quit the application. I initially had the problem some time ago and it went away when a update to the drivers was released (not sure which version). The problem has returned with the new release of the last couple updates.
