Once a screen is captured, AIUI, the Window Server is not guaranteed
to be in a usable state. I believe this can cause problems on some
GPUs more than others. If it's working for you, maybe it's less of a
problem nowadays.

Short answer: you cannot mix AppKit with a captured screen. (I'm
assuming your floating window is some instance of NSWindow and the
full-screen presentation your talking about has already captured
the screen with the CG API calls)
If the display has already been captured, you'll need to do
drawing yourself onto it.
Would you mind to elaborate a little bit? I have a shipping (single
window) kiosk app that captures the main screen and does some
Frontrow-esque stuff in the main NSWindow (with a dynamically
changing set of NSViews subclasses)... It's in a "controlled
environment", but none of the four test machine-types had any
problems besides the coordinate system that does not get reset
instantly after changing the resolution....
