Whenever I launch Dark Radiant, it doesn't properly display anything beside the toolbars. Instead, the screens stay white or repeat frame borders and other artifacts when I manually resize the program window. I've attached a screenshot to show what I mean. The editor is not usable under this condition because it doesn't refresh to show work done. I'm using the Win 64bit version of Dark Radiant on Windows 7, a GTX 275 card and its latest 191.07 NVIDIA drivers. The path to Doom 3 is correct, although it's not on the default C:\. TDM plays just fine. Has anyone had similar problems? I assume it's some kind of video driver/program rendering problem? (Edit: It seems I can't make attachments yet...)
