Hi Roman, I haven't tried using FBO with GLES2 so can't comment on specifics. The best I can do is suggest having a look at the OpenScenegGraph/src/osg/FrameBufferObject.cpp when you run your app with a debugger or added debug messages to see what the class is doing when you using with X11/OpenGL vs GLES2. It could be that feature is not detected and setup correctly under GLES2 by the OSG, or perhaps simply that GLES2 driver doesn't fully support FBO or the specific format you want to use.
