- Suggestion from Kelly Brock <kbrock@8cs.com> (not yet implemented):
-
- OpenGL corruption fix is simple assuming it doesn't screw anything else
- up. Add the following line to the top of the create function:
-
- wxSize parentSize = GetClientSize();
-
- All locations within the function that use 'size' are changed to
- 'parentSize'.
- The above corrects the initial display corruption with the GeForce and
- TNT2, not sure about other NVidia cards yet.
