When trying to get a snapshot from wayland, I only get a white cairo.surface.
When trying to get a snapshot from Xorg, it works.
On Wayland, adding WEBKIT_DISABLE_COMPOSITING_MODE" == "1" fix the issue.

FWIW I'm 100% sure it works fine in Epiphany, as we use this API to take overview snapshots and I would certainly have noticed if that was broken. What version of WebKitGTK+ are you using?
Michael Catanzaro
Ah wait, this API is racy and impossible to use correctly. Could you be hitting bug #164180? That issue is timing-dependent and so it would not be surprising if you get different results in Wayland.
Cédric Bellegarde
Using get_snapshot delayed (10 seconds) doesn't fix the issue. So not an issue with page not rendered.

And my webkit version is:
$ pacman -Q|grep webkit2
webkit2gtk 2.14.3-1

Closing, don't find what is wrong in my code but trying with a simple webview, it works.
