Sorry, i forgot to remove it. I updated post.
@bronstein87 - cool, I also removed everything related to 'backend.h' and your code runs, what is the problem?, did you try running the code with all backend stuff removed?, what is it you are trying to achieve exactly?

@Markkyboy Problem is that after compilation i see just an empty window. Like this:
And in every other application with qml i see just an empty window. (i tried many apps from qt library of examples) -

I'm using Windows 7 Ultimate x64 with QtCreator 4.11.1 (MSVC 2017, 32bit) and your code works when all backend related stuff is removed.
Could it be a Windows10 problem I wonder?, I don't know what else to say, sorry.

(i tried many apps from qt library of examples)@bronstein87 - I suggest scrapping the current project and starting again. looking at your screenshot, I see remains of 'backend' files, perhaps this is causing problems?, admittedly, this is all guess work on my behalf.
For what it is worth, here is a screenshot of my set up running your code;

I think something is missing in the system, maybe some libraries or paths are missing. or some wrong settings in qt itself -

@jsulm Hi. I made clean and rebuilt project. And how you can see there is no any warnings or unusual messages...
@bronstein87 might be a driver / open gl issue
what os do you use and what graphic-card and are those drivers up to date?

@J-Hilk Hi. I also thought about that, but drivers up to date (i have just checked).
OS - win10 x64, graphic-card - GeForce RTX 2060 SUPER. -

@J-Hilk I added this attribute and now everything works
QCoreApplication::setAttribute(Qt::AA_UseSoftwareOpenGL );But it seems to me that usage of software opengl is not a good idea in terms of performance. Do you have any thoughts about how to force it to work with Qt::AA_UseDesktopOpenGL ?

@bronstein87 Are you working per remote session (TeamViewer) or directly on PC? I've got troubles with QML/OpenGL and TeamViewer and often only got an empty view.
If you are using TeamViewer, take at look at this thread: https://community.teamviewer.com/t5/General-Questions/Some-applications-does-not-show-content-white-window-Windows-10/td-p/10718
