Hi Lionel,
I have not looked in close detail, but SaWMan has an optimization to
align the layer to the window if only one window is displayed - this
holds for size and location. I think you are hitting this, but I don't
know why it would go from double to single bufferend in that case.
The switching behaviour can be prevented by having the SaWMan callback
layer_reconfig() disallowing all changes (not returning DFB_OK).

Hi all,
I'm playing a little bit with SaWMan these days, and I noticed a
strange flicking effect.
Here is my setup :
- a 1280x720 layer double buffered at start
- a 1280x720 window containing a main application
- 2/3 300x200 windows acting as widgets on top of the main application window
When I destroy the 300x200 windows, and then I recreate one of them,
I'm noticing a
flickering effect of the whole screen. With a few investigation I
found that at this moment,
SaWMan reconfigure the layer to change its buffermode from double
buffered to single
buffered.
Any explanation ?
Regards,
