[PATCH 3/5] present: Add mode for pixmap flips per window
Roman Gilg
subdiff at gmail.com
Tue Aug 29 15:24:30 UTC 2017
This patch adds a new mode to the internal flip mode API, that
enables per window flips on capable hardware platforms.
Pixmap flips are possible for every window with a parent window and
without redirection.
Besides the per window flips the new mode diverges from the old
screen flipping by holding back the PresentIdleNotify event for a
flipped pixmaps of a preceding frame until present_winmode_event_notify
is called once more.
The mode is initialized by calling present_winmode_screen_init instead
of present_screen_init for a particular ScreenPtr.
