OpenGL stereo window flashing in Quadro drivers December 2020 to at least July 2021

DAT/EM’s stereoplotter application uses OpenGL stereo. Our customers have Quadro K-, M-, P-, and RTX video cards. Most have old 3DVision 2 Kits with Onboard DIN Connector settings, but some use clone mode with modern dual-screen mirror displays such as PluraView and Sonic4. In all Quadro drivers from December 2020 to at least July 2021, the OpenGL stereo view flashes on panning and zooming the images. Reinstalling the October 2020 video driver 452.57 cures the problem. We don’t like having to recommend old video drivers, so would appreciate a fix in future drivers or information on how to stop the flashing problem in current drivers.
