[ISSUE] shadow buffer not copied inside the frame buffer

Then when I start weston with:
 --backend=fbdev-backend.so --modules=tablet-shell.so --device=/dev/fb0
desktop-shell.so and tablet-shell.so seem to be started in the same time
and tablet-shell.so cover some parts of desktop-shell.so.
if I start weston with:
 --backend=fbdev-backend.so --device=/dev/fb0
and inside weston.ini with:
The background (homescreen) flashes and the screen becomes black.

Then I suppose that tablet-shell.so is buggy first and the mix of two
shells is not recommended.

When I start weston with only the desktop-shell.so, it seems to work.

One day and an half loose.
