Subject: Problems implementing double buffered painting for Windows
Date: Mon, 11 May 2020 12:13:50 +0200 [thread overview]
Message-ID: <86wo5ig4o1.fsf@inmotica-integral.es> (raw)
Hello,
I'm trying to implement double buffered painting for Windows, to
eliminate flicker. I am encountering some problems:
- When to flip buffers? I have tried to attach the flip to
frame_up_to_date_hook on the 'terminal' struct, but it sometimes get
called when it should not, producing flicker.
- What portion of the screen has been updated? I have seen no clear way
to find this out. I'm resorting to intercept calls to w32_fill_rect to
mark areas as invalidated, as it /seems/ to be always used to clean
the area before painting, but this is clearly not a solution.
Any ideas welcome. Thank you.
