After a few minutes of starting the same effect is produced as in XFCE
4.16 with the Compositor activated, the screen freezes, the mouse cursor
moves but the buttons do not respond.

I am now using XFCE 4.10, the version that came with Jessie, with
Compositor enabled and I am not experiencing screen freezes.
