It might be related to GPU load, e.g. to the GPU memory clock being changed dynamically. You could try if forcing the clock to a certain value avoids the problem. -- Earthling Michel Dänzer | https://www.amd.com Libre software enthusiast | Mesa and X developer

This is a DC issue which is fixed in current 4.16.y upstream. Hi, not sure this was the issue or maybe the root cause is somewhere else. I got my graphics card replaced in the meantime (now a RX580) and the problem still appears, although less frequent. I can reproduce it well when screen config is set to 2560x1440 and 75Hz, latest Sid version of xserver-xorg-video-amdgpu. Example: for a still image, there are no issues, but when I open Firefox in background (maximized) and I start moving the gvim window (mail editor) around the screen in circles then it flickers at least once per second, often even faster. And the temporarily visible overlay looks more like garbage (i.e. it feels like a quick GPU restart). The flickering is much less disturbing if the moved window is a simple one, like xterm, so it might have some connection to the drawing performance? 60Hz mode is okay, though. And there are no such issues with Windows. Also, I have had a 4K monitor here once (60Hz device) and there were no such problems IIRC.

That's because DC is enabled by default for you, you need amdgpu.dc=0 to disable it. This is a DC issue which is fixed in current 4.16.y upstream. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer

Package: xserver-xorg-video-amdgpu Version: 18.0.1-1 Severity: normal Hello, my card (cheaper version of Rx560) has been working quite well for months. But I made a dist-upgrade a few weeks ago and since then I see strange flickering happening every few minutes, sometimes even multiple times per minute. Feels like a quick insertion of a black frame. Maybe a silent GPU reset or something? It seems to happen more often when mouse is moving and/or Firefox is active. First I suspected the application where I saw it most in the first days (another web browser) but now I see this happen from time to time with other applications, like the gvim window I see in front of me right now. First I attribute this to the amdgpu.dc=1 kernel option which I have set for testing purposes before, but removing it did not change the behavior. Temps are normal. The is no such problem with Windows! $ sensors amdgpu-pci-0100 Adapter: PCI adapter fan1: 974 RPM temp1:+31.0°C (crit = +0.0°C, hyst = +0.0°C) Regards, Eduard. -- Package-specific info: X server symlink status: lrwxrwxrwx 1 root root 13 Jun 1 2009 /etc/X11/X -> /usr/bin/Xorg -rwxr-xr-x 1 root root 274 Jan 18 13:11 /usr/bin/Xorg VGA-compatible devices on PCI bus: -- 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
