dmesg from drm-intel-next-queued (34730fed)
(In reply to Maarten Lankhorst from <a href="show_bug.cgi?id=97242#c5">comment #5</a>)
<span class="quote">> Some watermark fixes have also been applied to drm-intel-next-queued,

The heavy cursor flickering is gone in drm-intel-next-queued, but the cursor
now behaves funny when moving between screens:
1. It usually moves directly to the opposite edge of the screen. It seems like
the acceleration cannot be calculated correctly. This might also be an X issue.
2. Whenever the mouse cursor changes screens, I get a short screen
distortion/flickering in the upper left-hand corner of the display which the
cursor has left.
But at least the machine is usable again. I hope these fixes will make it into
4.8, as otherwise this Kernel release will be a no-go for dual-screen users.
And finally, I am encountering a completely new issue (I'll open a separate bug
report for this):
The screens now flicker randomly (like once or twice every other minute). This
is unrelated to cursor movements, so it probably does not have anything to do
with this bug report.
I have attached a system log with drm.debug=0xe.</pre>
