Stencil buffer doesn't work in fullscreen

I noticed a very curious thing: real time shadows with the stencil buffer won't work in any full screen video mode. Also Special Fx demo behaves so, so I am sure it's not a bug in my coding.
Now, is it a bug (it would be a GREAT bug) or I missed some step? thanks!!

Stencil buffer in fullscreen works fine on my case both in
DX and OGL, just curious what irrlicht version you are using,
and video card type?

I am using irrlicht version 0.14, and I have an GeForce 4 MX.
Probably the problem is my videocard, cause I noticed in the console that irrlicht says that "depth stencil buffer is not compatibile with video format", or something like that, everytime I start the program in full screen mode

depth stencil buffer is not compatibile with video format

Try messing with your bit depth, try setting it to 16 or 32 and see if it works then.

On my older graphics card, I have noticed the same thing. But frame rates in windowed mode with shadows are so low it's pointless to even run them.

Mind you, even on my high end graphics card I take a huge hit with shadows. In the order of 800 fps, but the game is still at acceptable frame rates of 500+.

Right..same problem here. With my GeForceMX real time shadow wont work at all (16/32) in the fullscreen
may the *g force be with us.[/b]

By the way this should be a bug cause others application(non-Irrlicht) work with realtime shadows in fullscreen mode.
