X server log

Hi all,

I'm using Arch Linux with kernel 4.13.5-1-ARCH, Xorg 1.19.5 and the amdgpu
driver, version 1.4. My GPU is a R9 390. I attached the X server log.
My window manager is i3.

Entries in xorg.conf.d:

20-amdgpu.conf

Section "Device"
        Identifier "AMD R9 390"
        Driver "amdgpu"
        Option "DRI" "3"
        Option "TearFree" "true"
EndSection

With this setup I experience screen tearing and flickering on a WQHD monito=
r.
Enabling a compositor like compton makes these effects worse.
I can reproduce this issue on the same machine with KDE instead of i3.
To give you an idea of my problem, I captured a scene from the RTS 0ad:

The same kind of flickering and tearing also happens in desktop mode. It se=
ems
to appear randomly.
However, the problem disappears when I'm using the radeonsi driver or chang=
ing
the resolution to FHD. In both cases everything is fine.
