I add the logging statements like you suggest. I obtain:
Start view with render on video
/When pass in GLDrawContext_New  theDrawContext is 02344c98 /
Call render in the pixmap drawcontext
/When pass in  gldrawcontext_fbo_new  (//ofcourse after call to 
Q3Object_GetPoperty(...KQ3DrawContextPropertyAcceleretedOffscreen...))// 
masterDrawContext 02344c98.

/After I recreate a window on screen with a new draw context /
/For create the bitmap after render I use  Q3View_GetDrawContext and 
Q3PixmapDrawContext_GetPixmap maybe my problem here?
