Windows 8 shows the windows of my application empty.

Hi,
What kind of application is it ?
What version of Qt are you using ?
What is different in the Win8 machine from the other (specifically graphic hardware wise).

@SGaist Thank you for the fast response.
-It is a download manager desktop application. The OS targets are: Windows 7,8,10 and Mac OS. (For Win8 we don't need Metro UI, but just the regular desktop one)
-I am using QT 5.3.2 (for some special reasons I need to stick to this version for now).
-The Win8 (64 bits version) is a ISO mounted in a Oracle Virtual Machine in the same Mac where the application runs without problems. We have additionally a Windows 7 host with also a Win8 ISO mounted in a Oracle VM. In both the app works perfectly in the host OS but not in the Win8 VM. Therefore I suppose the hardware setup doesn't play any role.
Please just tell me if you need any further info, thanks!

and what version exactly? the ANGLE or OpenGL variant?
The dynamic OpenGL option was added since Qt 5.4. -

http://download.qt.io/archive/qt/5.3/5.3.2/qt-opensource-windows-x86-mingw482_opengl-5.3.2.exeWhat is exactly "dynamic OpenGL"? is this feature needed in order to work properly with Win8?
Thank you for the support.

Read this.
When using the OpenGL(-only) version as you do, you need to make sure that OpenGL is available on the machine. Means a compatible graphic card driver is installed. Also i would check the VM settings to use hardware accelerated graphics then.
I was asking about which version, because this shouldn't be an issue with Qt 5.4 onwards, since it automatically falls back to ANGLE (DirectX) if OpenGL isn't available.

@raven-worx Indeed it seems a problem with OpenGL and the Win8 Virtual Box driver. I had the chance to test the app in a native Win8 and it works as expected.
Thank you very much!!
