[SDL] viewport bigger than display size issue

Hello,
I am using the back buffer to process some OpenGL textures.
When I define a viewport that is bigger than the display rectangle, any data
drawn outside of the display rectangle are lost. (eg. display window: 320,
200 / viewport: 512, 512 )

Is it an expected behavior ?

(using SDL 1.2 on Windows XP)

Thanks for any help,
Franck.
