posRelative.y = posAbsolute.y;

Now, I'd say that there's only a small chance that you can get this working better than the automatic DXGI implementation. This kind of issue is highly dependent on the adapter vendor, driver ...

I've run into something sort of similar, and the quick answer is that once windows starts processing the quit, you don't have a lot of time. Controls and resources start getting destroyed immediately, and it is entirely possible that by the time your thread gets around to referencing the resource, it's already extinct.
I got around this by intercepting the ...
