[E-devel] enlightenment blanking issue

Hi
I don't understand why, sometimes, screen blanking doesn't work on
enlightenment.
Most of time, it works but sometimes not. Before I thought this issue
comes from intel driver (modesetting i915) but now, i'm sure this not
the case because i get same issue when i launch enlightenment using
nvidia driver (optimus technology)
Conditions: enlightenment-git efl-git
Settings:
screen blanking  2.2 minutes
DPMS
