screen shot of black border problem
After playing games in Manjaro, I get black borders and screen flickering and distortion. Hitting turning off compositing with Alt+Shift+F12 gets rid of the problem, but it comes right back when I turn it back on. Session must be totally exited and restarted before it will return to normal. Happens on either Steam or non-steam games.
I'm running Manjaro 15.12 with the 2016-03-30 update, KDE 5.6.1, and the Linux 4.4.6-1 kernel. This particular problem was not present until this update.
please attach the output of "qdbus org.kde.KWin /KWin supportInformation" to the other bug.
