Bug Description

On ASRock QC5000M-ITX/PH P1.10 and BIOSTAR Group A68N-2100 4.6.5 the mouse cursor is displayed distorted since we upgraded to kernel linux-image-4.4.0-75-generic:amd64

We use 32bit Xubuntu 14.04.5 with 64bit Kernel on about 150 machines. Core2Duo, Celeron and Atom seems all fine, only the AMD machines with the mentioned SOC boards have this issue.

We never had this issue beginning from Kernel 3.16 via 4.2 up to 4.4.0-72 - so we will use that one. I installed the latest 4.2, 4.4.0-21, 4.4.0-66, 4.4.0-71 and 4.4.0-72 and the issue is absent.

The issue occurs with the default mouse cursor and with comixcursors-righthanded-opaque (which we use).

The distortion is like the width stays the same, but the height gets halved.

I will try the mainline kernel tomorrow. I can say it does not happen with Ubuntu 16.04 and seems to be related to 64bit kernels on a 32bit system. It doesnt happen with 32bit kernels.
