Comment # 19 on bug 1014999 from Anthony Hughes

I just wanted to mention that I hit this frequently with the KDE desktop in
Leap 42.2 and thought it was a KDE issue so I reinstalled with Gnome 3.20.2 but
experience it in both environments. My setup is a Lenovo Thinkpad x260 with an
Intel(R) HD Graphics 520 (Skylake GT2) with a 1080p monitor connected via
mini-displayport to HDMI (ie. laptop <> minidp <> hdmi <> monitor). My monitor
is configured as the secondary display oriented above my main display. It
happens once a day on average.

Please let me know if there's any logging or debug info I can provide to
support this bug.
