Dear Coot-ers!

With the observation that 3D vision works in a Windows environment without
the need for a Quadro card, I was trying out all the usual 3D visualization
programs to see if they could display a stereo image. I could get Chimera
and Pymol to display a quad-buffered stereoscopic image using my current
system in fullscreen mode (Windowed mode does not work, if you have any
suggestions for this, that would be also great to hear)

Graphics card: NVIDIA RTX 2070
NVIDIA driver: 425.31 (3D vision archive version)
Windows Version: 10.0.17763 Build 17763

However WinCoot (0.8.9.2-pre EL rev. 7835) does not seem to want to do it.
When I enable hardware stereo mode, I can see that the hardware indeed does
engage 3D mode (the IR emitter shows green light, and my monitor gets
darker), however there model/map that was displayed just disappears and
only a black screen is in view. Going to full-screen mode does not change
anything, and disabling the stereo mode brings the model/map back (in 2D).
Opening a new model/map also shows nothing.

I have already disabled Triple buffering, Threaded optimization, and Vsync
in the NVIDIA control panel. I should note that in my version the "enable
stereo" option is not present. However as Chimera and Pymol seem to be
alright with it, I am inclined to think maybe something can be done to make
it work in Coot too.

Any suggestions would be much appreciated

Best wishes
Shintaro
