Commen= t # 13 on bug 98897<= /a> from berg 
I can confirm this bug does not affect 4.8.6 kernel on MacBook=
 Pro 11,5.

I built the 4.8.6 kernel this morning and do not have the same flickering
problem as I had 4.8.7 onward. I did notice a very big jump in GPU performa=
nce
though from 4.7.0 to 4.8.6 (around 35-40% improvement on OpenGL benchmark) =
on
the MacBook Pro 11,5 with the radeon driver.=20

I did find that the GPU fan was full speed on initial first boot on 4.8.6+,
noticeably very noisy but quietened down after some time.

While I'm not experiencing any flickering on 4.8.6, I have noticed some sub=
tle
screen tearing on Gnome Shell transitions; such as when you hit the super k=
ey.
In the past with the fglrx driver, there was an option to enable in the ATI=
/AMD
configuration manager to address this tearing. I just noticed this tearing =
as I
was looking for the flickering that this bug mentions.
