QML autoscale bug

There are 3 monitors connected to the PC: left and rifgt are FullHD (scale 100%) and the central one is 4K (scale 150%).

When I create a test project with autoscle QML scene I stumbled on this issue. When I move programm window from one monitor to the other, programm window can be scaled correctly but what is inside the window may be displayed incorrectly. Sometimes at may lead to cycling issue and programm will crash. On the attached video I tried to show you what is happenning to the programm window.

In the beginning of the video I show you test project, which is available over the link below. Then in the end of the video I showed you the window of the project I'm working on (it's more complicated, but graphical part is the same to the test project) though behaviour of the main and test projectsis different.

Both projects were complied on Qt5.13 with mingw and VS2017, the result is the same.
