Regarding to xcb_present_pixmap client call, you might have to check xserver present/present.c on how xserver deal with it.

Hi Leo,

To support clipping of the output texture I was trying to send a xcb_xfixes_region as the fifth argument (i.e valid-area) to xcb_present_pixmap but it still displays the entire surface. Am I missing something?

Regards,
Nayan
