White Screen - Graphics Card Problem?

Lately I’ve been having trouble initializing the graphics windows of my GL applications. The window border comes up o.k. but it’s all white inside the window where the graphics should be. Sometimes the window doesn’t clear to any color, so whatever’s on the desktop shows through. Usually if I try to load the app 2 or 3 times, it comes up successfully. This is happening with two of my larger applications. Could this be a problem with my video card? Anyone seen this type of behavior? Thanks.

Out of curiosity, what video card and driver version?

Never seen an issue like that across many ATI and nVidia gfx cards and various flavours of Windows. Are you using 3rd party window management ?
