Comment 1 Eike Hein 2018-05-28 18:07:28 UTC 
Fixed in newer Qt

*** This bug has been marked as a duplicate of bug 369430 ***
Comment 2 Christoph Feck 2018-06-28 00:20:45 UTC 
Eike, which Qt version has the fix? See also bug 395229 with Qt 5.11.0.
Comment 3 Eike Hein 2018-06-28 12:02:19 UTC 
It looks like these could be different issues after all ...
