As previously discussed, the DRI3 plus modesetting driver combination is known to be broken in accelerated compositing mode as per [1]. WebKitWebViews will most likely not be functional in F25 for affected users. Any help in fixing [1] would of course be appreciated. The relevant upstream WebKit developers are not very interested in this problem because Debian doesn't use DRI3.
