The keyword being 'reduce'. This won't reliably prevent tearing in
general, so I'm not sure I see the point of jumping through all those hoops.

If glamor Xv used (something like) present_pixmap(), that would reliably
prevent tearing at least in the fullscreen case, wouldn't it?

If you don't want any tearing ever, use a Wayland compositor? :)
