The short-curcuit introduced by commit 963b5bb (later modified by commit aacc344) breaks XShmGetImage().
Images captured by ffmpeg's x11grab or x11vnc become choppy, while I use Cinnamon Desktop Environment.
I tested on:
i5-4570 (Haswell) and B85 Chipset
Fedora 24 (Developmental Branch) x86_64
Cinnamon 2.8.7
