macOS issue: Detaching native window such as QVulkanWindow causes a huge memory leak.

When adding a native window as a tab, a large memory leak occurs (from ~200MB to 1.5GB RAM). I managed to solve this problem by setting this attribute: QWidget::setAttribute(Qt::WA_DontCreateNativeAncestors) to window container.
Now native windows are not created for all widgets in the application. But when I undock this widget into floating window, the RAM again becomes about 1.5GB. I suspect this may also be due to the creation of native ancestors.
Do you have any idea why this is happening? I think the problem is somewhere on the surface. I'm using Qt 6.5.2.
No, sorry - no idea. I have no Mac and also the number of Mac ADS user is very small. So you are at your own fixing this issue.
Our cross platform app uses QtADS but we are using OpenGL with VTK. We are using Qt 6.5.x for the gui. We have not seen anything
I do not think, that this is an ADS issue and I cannot reproduce it because I have no Mac.
