--- Comment #25 from Sandor Geller wildy73@gmail.com --- Reinstalled Warcraft III: Reign of Chaos without an active internet connection so it remained at v1.14. This version changes the screen resolution instead of scaling and worked prefectly both in windowed and in OpenGL mode so I can confirm that the issue I had is no longer present. I tested using wine version 2.21.
