Black screen in Qt Quick 5.5 app, but only on Win2008

IAmHe

I'm working on a 64-bit app, developed with Qt Quick v5.5, compiled with with MSVC 2013. It runs fine on x64 Windows versions 7, 2010, and 2012 R2. However, on Windows 2008 and 2008 R2, it produces a black screen.

All systems mentioned are VMs.

If anyone has encountered this, and can knows what might be happening, it would be greatly appreciated. Even just a starting point on where to look would be of benefit.

Is there a particular set of logs I can examine, or provide here, to supply additional context for this issue?

Thanks very much,

Hi and welcome to devnet,

You should check the graphics driver you have available for that machine.

@SGaist Hi, Thanks very much for your reply.

I did compare the graphics card settings to that of my VM's that do not exhibit the problem, but I don't see any significant differences. Do you know any specific settings/features to compare?

Thank you!

What differences where there ?

What about the host machines ?

@SGaist I am experiencing the same issue, the app will go black seemingly at random, but apparently during a redraw. The cursor remains, and it is not recoverable. This is a Qt 5.7 commercial app and the VM happens to be Windows 8.1. What should we check regarding graphics driver?
