Bug ID: 103317 Summary: Tearing in WQHD, but not in FHD Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: torkes94@gmail.com

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 monitor. 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 seems to appear randomly. However, the problem disappears when I'm using the radeonsi driver or changing the resolution to FHD. In both cases everything is fine.
