Title:
Bionic: OpenGL not properly working with Intel IGP
Status in mesa-utils package in Ubuntu:

Status in xserver-xorg-video-intel package in Ubuntu:

Bug description:
Hi,
I'm running Ubuntu 18.04 Bionic daily with proposed updates enabled. I
am using gnome-flashback (gnome-panel) with Compiz. I first recognised
that Compiz is giving very high CPU loads according to top. At the
same time, intel_gpu_top shows GPU usage at an unchanged 0%. The same
happens when running glmark2: CPU usage climbs to >400% while GPU
stays at 0%. Interestingly, OpenGL seems to be enabled - please see
the glxinfo outputs below. Switching to todays latest oibaf drivers
did not make any difference.
Any pointers are much appreciated.
r.
