UPDATE:

since I am using Kernel 4.4.0-10#25 the bug is gone.

Saturday I am going to bisect into the problem.
How do I report the broken commit? do I just paste the commit id?

just booted from the xenial daily stick which I used for installation. 
with kernel 4.4.0.10 the problem did not occur. i am not sure how i can 
reinstall that specific kernel version.
i would like to give the kernel a try before bisecting to problem.

2016-03-29 Thread Thiago Martins
Joseph,

Earlier versions of Xenial, doesn't have this problem.

Maybe with previous XOrg / Linux 4.3 combo... And also, maybe two or
three Google Chrome previous versions?

I think that it would be a good idea to give it a try, maybe a Xenial
alpha.

Best!
Thiago

2016-03-29 Thread Joseph Salisbury
Did this issue start happening after an update/upgrade? Was there a
kernel version where you were not having this particular problem? This
will help determine if the problem you are seeing is the result of a
regression, and when this regression was introduced.   If this is a
regression, we can perform a kernel bisect to identify the commit that
introduced the problem.

Hey!

I'm also facing this problem, I recorded a video about it:

https://www.youtube.com/watch?v=l21WsKz3fZc

I tried to move away from XOrg, by using GNOME+Wayland, but, problem
persist, Wayland is faster, however, I can still see it flickering
(faster).

Problem with GNOME+Wayland is that it completely freezes my Macbook.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.5 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.
