I have a Qt::ToolTip window which should show in a specific place, similar to Qt Creator's LocatorPopup. ( when you pressed cmd + k).
But the app receives SIGSEGV while trying to access QPlatformWindow::window() in qnsview_mouse.mm:
To reproduce this (in my case), a user should press on a specific place on the border of windows near Qt::ToolTip window border. See videos.
The issue not happened if I changed Qt::ToolTip to Qt::Popup. But this is not an option for me.
Attached example and videos. (with Qt Creator steps and crash report)
