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.

Hello,
If you are targeting Windoows10, you could try to use Direct3D 12
renderer with Qt 5.15.x

Windows NVIDIA GPU
Hello everyone.
I’ve been having this issue on NVIDIA cards on Windows in all versions
from Qt v5.12.2 to v5.15.0. I created a ticket here:
https://bugreports.qt.io/browse/QTBUG-85524
But I wanted to reach out to see If anybody else encountered this. I’m
not that well versed in this issue. I’m trying to research to see If
there’s anything I can do about it or find a work around. There’s a
few other related tickets in QTBUG but they don’t really offer a clear
(At least to me) definition of the problem.
If anyone with the same problem can share their experience or provide
any insight, I’d appreciate it.
Regards,
Furkan Üzümcü
