Are you using Wayland ?

[Antonio Trande]

Yes, it's by default on f25.
LiVES works if i use Xorg instead of Wayland.

[Salsaman]

OK. I don't have Wayland here to test with, but I made a patch in svn. Would you mind testing the svn version ?

[Antonio Trande]

svn-2608 works both with Xorg and Wayland.

[Antonio Trande]

r2608 ?
