The solution for to refactor the way that events are checked so I add a bool return type to checkEvents() method across osgViewer::GraphcisWindow, osgGA::Devive and osgViewer::Viewer/CompositeViewer classes
To reproduce the problem I attach a minimally modified osgviewer that just prints resize events. You can check what's printed in the console when you go fullscreen and windowed a few times.
The attached version of GraphicsWindowX11 fixes the problem for me, but I'm not sure this is the right approach. Maybe you can see a fix for the problem clearer.
The only place where the RESIZE event is generated in GraphicsWindowX11 is in CheckEvents and it then depends on the ConfigureNotify message. For some reason, either ConfigureNotify is not sent when going fullscreen or the traits already reflect the latest window size."

that the windows did not act on repaint request (WM_PAINT, EXPOSE,...)
Detailed explanation:
- I implemented requestRedraw using the push approach (not using
GraphicsWindow::_requestRedraw flag that I was considering) as there may be
multiple viewers reading the flag and fighting to reset it after the paint
request, while some viewers may not spot the request to redraw
- I made windows call GraphicsWindow::requestRedraw when they receive
appropriate message (WM_PAINT, EXPOSE, RESIZE,...)
- There were issues on Linux that windows did not want to close using x
button. Resolved by moving the test for DeleteWindow event from
swapBuffersImplementation() to GraphicsWindowX11::checkEvents(). The difficulty
was that DeleteWindow event is not coming using _eventDisplay, but through
_display.
- The last difficulty was that it is necessary to call
ViewerBase::checkWindowStatus() to set _done to true when all windows are
closed. This did not happened recently in ON_DEMAND run scheme. I put the call
to checkWindowStatus() to eventTraversal.

and another problem is:
example osgkeyboard is not work (keys not highlight) if user have 2 keyboard layout native and english and current user layout is native
I try to explain my changes
we need something that is identify key without modifier keys and layout -> this is UnmodifedKey
I think osg must have its own UnmodifiedKeys table. Code must be run same on different platforms. This can de guaranteed by UnmodifiedKeys table.
Mikhail Izmestev helped me. He implemented VirtualKey changes in GraphicsWindowX11"
osg::GraphicsContext, in order to give good integration with the
application's GUI toolkit. This works really well.
However, I need to share OpenGL texture resources with the standard
osgViewer GraphicsContext implementations, in particular the
PixelBuffers. This is essential for my application to conserve graphics
memory on low-end hardware. Currently the standard osg implementations
will not share resources with another derived osg::GraphicsContext,
other than the pre-defined osgViewer classes e.g. PixelBufferX11 is
hardcoded to only share resources with GraphicsWindowX11 and
PixelBufferX11 objects, and no other osg::GraphicsContext object.
To address this in the cleanest way I could think of, I have moved the
OpenGL handle variables for each platform into a small utility class,
e.g. GraphicsHandleX11 for unix. Then GraphicsWindowX11, PixelBufferX11
and any other derived osg::GraphicsContext class can inherit from
GraphicsHandleX11 to share OpenGL resources.
I have updated the X11, Win32 and Carbon implementations to use this.
The changes are minor. I haven't touched the Cocoa implmentation as
I'm not familiar with it at all and couldn't test it - it will work
unchanged.
Without this I had some horrible hacks in my application, this greatly
simplifies things for me. It also simplifies the osgViewer
implementations slightly. Perhaps it may help with other users'
desires to share resources with external graphics contexts, as was
discussed on the user list recently."
Notes from Robert Osfield, adapted Colin's submission to work with the new EGL related changes.
For example, when running FlightGear, I want the window to always have no title, so it opens full-screen without using the --full-screen option, which would prevent other windows from moving above the osg window.
I am attaching a patch I made to fix this problem."
