Description mkkot 2018-06-13 15:46:35 UTC 
Hello,
please help to pin down following problem:

I noticed that there are some glitches in graphics after upgrade: http://img.koci.net.pl/?v=beznazwy.png

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:
https://git.archlinux.org/svntogit/packages.git/log/trunk?h=packages/xorg-server
https://git.archlinux.org/svntogit/packages.git/log/trunk?h=packages/xf86-video-ati

)

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?

Please attach your dmesg output and xorg log.
Comment 2 mkkot 2018-06-13 21:29:07 UTC 
Dmesg just after logging in: https://pastebin.com/mmnneiGK
Xorg.log (no errors here): https://pastebin.com/356UEFJA

Errors in dmesg are produced all the time and are visible in journalctl with always fresh timestamp.

This is probably fundamentally the same as bug 105381.

P.S. In the future please attach files here directly, don't reference external sites (especially not pastebins).
