DosBox Alt+Enter fails - "Ddraw created surface with wrong size"

trunk r70402 gcc dbg,

used ros with 1024x768 resolution.

When I tried to switch DosBox to fullscreen,
the operation failed and DosBox closed itself.
DosBox log notices "Ddraw_created_surface_with_wrong_size"

Did this work in the past / Is this a regression?
