In the freedoom options menu, the Graphic Detail switch is glitched because the High/Low graphics are too far to the left. I did some experimenting with it and I figured an ideal solution would be to change the graphics offsets to -15 for the X value
Fixed, but I am slightly concerned that it is just papering over the cracks of an engine deficiency, and will cause problems for any engine that tries to be more intelligent about setting out its menus.
