--- Comment #16 from Michel Dänzer michel@daenzer.net --- (In reply to blffkyzp from comment #15)
I am a normal user. Can you post the command lines i have to run as root or user?
I'm not familiar with the Linux distro you're using, please get help for this from somebody who is.
You also asked if the bug also occur with DRI3 disabled - can you give me the command line to run as root or user to disable this DRI3 thing?
Find the file in /usr/share/X11/xorg.conf.d/ or /etc/X11/xorg.conf.d/ which contains
Option "DRI3" "1"
and change it to "0".
