Original mailing list thread 12 months ago:
<a href="http://www.spinics.net/lists/intel-gfx/msg100776.html">http://www.spinics.net/lists/intel-gfx/msg100776.html</a>
Current thread (base on which product and component here selected):
<a href="https://lists.opensuse.org/opensuse-kernel/2017-07/msg00002.html">https://lists.opensuse.org/opensuse-kernel/2017-07/msg00002.html</a>
Dates back at least to kernel 3.16.7/server 1.16.1 in openSUSE 13.2.
Continues with kernel 4.11.6, with both openSUSE Tumbleweed 20170706 and 42.3,
& Debian 9.
Does not occur until Xorg server is started.
Occurs whether using intel(0) or modeset(0) driver.
Does not occur with Dell 760 Q43 8086:2e12 or Biostar G41 8086:2e32 Eaglelakes.
Nothing is apparently wrong in DE (Plasma,KDE3,TDE) usability.
