I am getting mouse flicker when using two gpus at once with 2 separated screens (one per gpu), The primary monitor gets most of the flickering but occasionally the secondary one does as well. Also the flickering tends to happen when moving the mouse. Also occasionally the mouse disappears.
The two gpus being used are a xfx-rx460 for the primary monitor (DVI cable)
And a r7-240 for the secondary monitor (VGA cable)
Both of the monitors are the same refresh rate and same resolution. Unfortunately its not currently possible for me to get a adapter to use different cables/gpuports.
I have tested this with a fresh install of Ubuntu 16.04 and the problem persisted, then I updated all the packages and kernel to the latest version of 16.04 (with the previous fresh install) reinstalled the drivers and the problem still persists.
I am using the latest available drivers from AMD, The AMDGPU-PRO 16.60
Running groups command does display the group "video"
uname -r gives: 4.4.0-59-generic
ASUS M5A97-R2 Motherboard
16 Gigs of ram
Fully updated fresh install of ubuntu 16.04
Thanks for any help
This problem has been fixed with the 17.10 patch.
