This is most likely related to OpenGL 2. The first thing you should do when seeing the blank screen is to make sure you are not running in fullscreen and then add the following line to your .pro file:
CONFIG += console
This will give you output when the program starts and may help you find out how to deploy the program.
Make sure to check the OpenGL version on your computer, you can use this [majorgeeks.com] program.
Your OpenGL version needs to be 2.0 (or higher). If it isn’t, try updating the drivers of your graphics card and check GLInfo for the OpenGL version.
I’d be interested to know if there’s a way to distribute OpenGL 2.0 with my program or at least use Qt to detect the OpenGL version on my PC so I can inform the user to update the graphics card drivers.
