Not that I'm aware of (whatever Fedora set up for this particular hardware).

00:02.0 Display controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core
Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 660
OEM] (rev a1)

I've gotten it down to test_SetWindowPos(). I'll narrow it down further next
