Fwd: [PATCH 5/5] xwayland: Pixmap flips of child windows on sub-surfaces

[Roman Gilg]

Sorry, apparently I didn't understand your explanation the last time. Can
you explain why non-Present requests need to see the sub-surface contents?
And how they see the contents of normal Wayland surfaces?

I don't see much of a difference in here. Both objects are black boxes in
terms of X and the only interfaces are input events and buffer content
delivery.
