Fullscreen in only one display using TwinView on Linux?

Hello everyone,
The SDL_FULLSCREEN mode on Linux works, but when using two physical
displays as a single X11 screen with the TwinView mode, SDL does not
detect that there are two displays, and covers both. This is nice for
some uses, but pretty annoying for most. In GTK+, a fullscreen window
covers only one of the two TwinView displays if there is more than

Is it planned to fix this in a near future? If so, is there any way we
can help with this? We should probably look in GTK+ to see how it is
