Hi,
>I will try to fix the Wayland issue (in fact unrelated to this patch)
As tested on:
SDL2-2.0.5-4.fc26.x86_64
xorg-x11-server-Xwayland-1.19.3-4.fc26.x86_64
weston-2.0.0-1.fc26.x86_64
xorg-x11-server-Xorg-1.19.3-4.fc26.x86_64
The attached mouse grab behavior reproducer utilizing how it is implemented on
SDL2 does work great on X11.
Not so on Wayland - on native server (/usr/bin/Xwayland) it sends just one
mouse motion and then it stops. It does work better on X11 server under Weston
but also not perfectly - one has to run 'weston --fullscreen' to test the
mouse motion properly but then Weston itself has a problem with the "wall" one
cannot cross further. (video link: https://youtu.be/AkXC-vXeKaY )
So I believe there is some more work on Wayland to do before one can make
a spice-gtk fix. I can look to fix the Weston "wall" problem first.
Thanks,
Steph
