<pre>Hello,
please help to pin down following problem:
I noticed that there are some glitches in graphics after upgrade:
<a href="http://img.koci.net.pl/?v=beznazwy.png">http://img.koci.net.pl/?v=beznazwy.png</a>
It is caused by those packages:
[2018-06-12 20:18] [ALPM] upgraded xf86-video-ati (1:18.0.1-1 -> 1:18.0.1-2)
[2018-06-12 20:18] [ALPM] upgraded xorg-server (1.19.6+13+gd0d1a694f-2 ->
1.20.0-7)
[2018-06-12 20:18] [ALPM] upgraded xorg-server-xvfb (1.19.6+13+gd0d1a694f-2 ->
1.20.0-7)
If you downgrade packages to mentioned versions, problem goes away.
(you can browse changes in Archlinux packages at:
<a href="https://git.archlinux.org/svntogit/packages.git/log/trunk?h=packages/xorg-server">https://git.archlinux.org/svntogit/packages.git/log/trunk?h=packages/xorg-server</a>
<a href="https://git.archlinux.org/svntogit/packages.git/log/trunk?h=packages/xf86-video-ati">https://git.archlinux.org/svntogit/packages.git/log/trunk?h=packages/xf86-video-ati</a>
)
Also my dmesg is full of messages like:
[ 400.831919] VM fault (0x04, vmid 2) at page 1084047, write from 'CB0'
(0x43423000) (0)
[ 400.831995] radeon 0000:00:01.0: GPU fault detected: 146 0x0be50014
[ 400.831996] radeon 0000:00:01.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000
[ 400.831997] radeon 0000:00:01.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS
0x0400000C
I noticed screen full of those messages while switching screens with alt + ctrl
+ F1-F7.
I'm running AMD APU on a PC: AMD A8-7600 Radeon R7, 10 Compute Cores 4C+6G.

I don't know if this is enough information, what else I can check?</pre>
