Hi Eron, I'm not a windows developer so can only comment in general. My thought is that it could well be an issue with the windowing systems addition of the shadow not playing well with double of the OpenGL window with the drivers you are using. I kinda doubt there there will be an option we can enable on the OSG side in the creation of the graphics context to fix this issue, and I there certainly there isn't any attempts at fixes checked in to address it which is not surprising as you are the first to report this issue.
The best I can recommend is try updating your OpenGL driver. Updating to the lastest OSG is very unlikely to help with this particular issue, but it may well be worth doing for all the other fruity goodness that it delivers ;-) Robert.
