dmesg

Hi all,

When using a kernel after the below commit, I get visual corruption only on the
right most vertical column of my screen:

Author: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
Date:   Mon Jul 23 14:13:23 2018 -0400

    drm/amd/display: Use calculated disp_clk_khz value for dce110

Using a kernel without this commit does not have the issue.

My GPU is a Sapphire Nitro+ Vega 64. I am using Gentoo with Mesa git and KDE
Plasma 5.

My main monitor is connected over DP and runs at 2560x1440 at 144hz. My second
monitor is connected over HDMI and runs at 1920x1080 at 60hz. I tried disabling
the second monitor in KDE, but the issue still occurs.

It also occurs in fullscreen applications.

I will also attach dmesg.

I can test any patches or answer any questions.

Thanks,
Sarnex
