QMacCocoaViewContainer broken in macOS 10.13 (High Sierra)

  • Example project
    Demonstration video

    If you compile example project against 5.11, 5.12 or 5.13, then run it in macOS 10.13 (High Sierra) you get 3 problems (well seen on the video):

    1. Segmented controls doesn't appear until you click them (in a real app, they also blink and hide/show)
    2. Spinbox doesn't change when you drag slider and it looks strange as well
    3. All cocoa controls disappear when you click on the wifi icon!

    If you compile this project against 5.6.3/5.9.8, it's totally fine. Basically our app doesn't work on macOS 10.13 while this OS is officially supported in Qt

    We submitted a bug QTBUG-78731 but the chance it will be reviewed and assigned is very low I'm afraid :(

    Any ideas? Workarounds? Fixed? Thanks.

    Qt 5.6.3
    Qt 5.13.1
