           Summary: Spinning wheel cursor splits into two parts when
                    starting laptop docked / using rotated external screen
           Product: xorg
           Version: git

Video showing the effect

I am using a Dell Latitude E5470 with then current intel driver from archlinux
64 bits, which is git commit 9fe04af4. As a desktop environment I am using i3
with compton as the compositor.

In case I start the X server with my laptop being docked with two additional
screens, one being rotated, animated cursors like the spinning wheel break up
into two parts on screen and rejoin with a fixed rate of maybe 1 Hz. I have
recorded a video for this, which will be attached. Funnily, recording the
desktop with byzanz or things like that does not contain these artifacts.

The issues only appears on the external screen which is not rotated. All
external screens are connected via display port. The internal screen is never
affected and also the rotated one is not. The issue seems to disappears once I
remove the rotation of one of the external screen and in several other
situations (related to screen layout changes, like undocking and docking again)
where I couldn't find a consistent pattern.
