I took some time to investigate this black screen issue found on some laptops (one of the has multi-touch and wacom pen input), and observed that the Ogre+Qt -compositing path functions correctly on these systems. I narrowed the issue down to finding the native HWND compositing to cover the 3D rendering surface.
As a workaround, I implemented a command-line flag -- ogrecapturetopwindow, which can be tried to have Ogre blit on top of the other window surfaces. See https://github.com/LudoCraft/Tundra/commit/4b90c28e9ab7c590f525237a946fd2e54cf992b6 . This was tested to work and cause no artifacts on the pen-enabled laptop, but the same mechanism on my desktop Win7 produces serious flickering artifacts with the native desktop compositing. At least it's a workaround that suits for now, pending until I have more time to revisit the issue.
