I can only re-produce it during the intro videos when the screen is 640x480. It seems to have nothing to do with OpenGL. Looks like windows is redrawing the window for some reason. Can't see why though.

Found the problem. Windows was clearing the window. Handling the WM_ERASEBKGND message solves the problem.

The issue was updated with the following change(s):
  • This issue has been closed
  • The status has been updated, from New to Fixed.
  • This issue's progression has been updated to 100 percent completed.
  • The resolution has been updated, from Not determined to RESOLVED.

I don't know, if this is something with ogl, but game is unplayable, when you alt+tab(you can play it, but it is uncomfortable)

The Erase Background thing was a red herring. Seems to be related to creating the OpenGL Window just before the resolution is changed. After moving the window creation after the resolution change i don't have the effect (Slight flicker for a split second but nothing constant).

Could you try the following:

Work good. When you go back to ow or start game, it fast blick for 1/7 of second maybie and after 1/7 second it is gone, but it does not matter.
