I'm seeing the issue with X11, I haven't built things for Wayland.  Before
doing that, I'd like to know how you're running things under Wayland...

* Have you build Wayland versions of Vulkan loader, Mesa and SachaWillems'
demos?  I.e. are you running the tests with XWayland, or pure Wayland?  (former
would hide the issue)

* If pure Wayland, are you running demos under gnome-shell, Weston, or
something else?  I.e. are the demos composited to fullscreen, which would also
invalidate your test results (copying the FB contents instead of flipping hides
the issue)?

At least Ubuntu 16.04 version of gnome-shell will composite fullscreen windows,
Weston I built from git few months ago, didn't composite (that were in native
monitor resolution)...
