Hi Timothy,
This is exactly how I implemented layers in our driver.
The layer visibility is set as pending when the layer is created - then on
a 'flip', 'set region' or 'update region' if it is still pending then it is
committed (made visible).
I can't comment on the correctness of this solution - other than to say it
seems to work ok here for directfb tests and gtk over dfb.
(this is dfb 0.9.24 btw).
HTH,
Jason Barstow,
