[Interest] QQuickWindow Transparent Window Issues on Windows NVIDIA GPU

[Henry Skoglund]

Hi, I think GTX 950M is too old (the laptop is from 2015) for Direct3D 
12, see for example: 
https://www.nvidia.com/en-us/geforce/forums/discover/234361/gtx-950m-dirextx-12/

Also, the driver for the Intel HD 4600 is a bit old, try updating it 
from 20.19.15.4549 to 20.19.15.4853, it might help for the transparency 
problem.
