visual.c:11146: Test failed: Got unexpected colour ffffbcbc.

This happens on all Windows versions available on that machine (from Windows
8.1 to Windows 10 2009). This failure also does not happen on any other machine
which makes it specific to Nvidia or this graphics card or this driver version
(391.35, the latest available at this date).
