Epiphany/WebKit logs

My Wayland desktop session freezes when I load a web video (for example,
YouTube) in a WebKitProcess Epiphany.

== Steps to Reproduce ==

1. Log into a Wayland session
2. Launch Epiphany
3. Load a youtube.com video

== Expected Results ==

The video plays.

== Actual Results ==

The desktop freezes until I remotely connect to the computer over SSH and kill
the WebKitProcess process rendering the content.

== Notes ==

This can be avoided by running epiphany with WEBKIT_DISABLE_COMPOSITING_MODE=1
set, which leads me to believe it is a nouveau bug (rather than a WebKit bug).
I've attached logs with Epiphany output. These two lines are particularly
concerning:

> Mar 15 07:20:03 bant org.gnome.Epiphany.desktop[14459]: WebKitWebProcess: pushbuf.c:727: nouveau_pushbuf_data: Assertion `kref' failed.
> Mar 15 07:20:16 bant org.gnome.Epiphany.desktop[14459]: nouveau: kernel rejected pushbuf: Device or resource busy
