<https://bugreports.qt.io/browse/PYSIDE-695> which is marked as a duplicate of <https://bugreports.qt.io/browse/QTBUG-68740>

Reproduced on macOS 10.15 with Pipe installed PySide2, i.e, Qt 5.15

The "fix" is to apply some sort of style sheet to the application. So looks like the same bug and should be reopened.

    Can you reproduce with the oldtestcase attached to QTBUG-68740 ?
    If yes then it's the same bug and it should be reopened.

    If only your new testcase can repro then it's a new bug. You reference 
    the old bug in case there's any good insights.

    I would also test with Qt6, as any fix should go there first.
