Comment 1 Matthieu Gallien 2018-04-07 08:27:23 UTC 
Thanks for your report.
Comment 2 Alexey Min 2018-04-10 09:24:45 UTC 
Looks similar or related to https://bugreports.qt.io/browse/QTBUG-63411 ?
Comment 3 Alexey Min 2018-04-12 12:25:32 UTC 
Looking forward to retest this with Qt 5.9.5, which changelog says they fixed something in QtWayland regarding showing/hiding windows - http://code.qt.io/cgit/qt/qtwayland.git/tree/dist/changes-5.9.5/?h=v5.9.5
Comment 4 Alexey Min 2018-04-21 17:02:35 UTC 
Re-tested, this crash is gone in Qt-5.9.5.
