<pre>Using the development version of Fedora 21, I can see Epiphany (GNOME's
WebKitGTK based browser) hang whenever a video is supposed to be presented
on-screen.
Running:
LIBGL_DRI3_DISABLE=1 epiphany
works around the problem.
mesa-dri-drivers-10.2.3-1.20140711.fc21.x86_64
kernel-3.16.0-0.rc5.git1.2.fc22.x86_64
Backtrace of the hang:
