Hi, I've seen this in ucsf chimera with quadro 1400 and 3400/3450 cards + nuvision emitter + CRT monitor. We fixed the issue by downgrading the nvidia driver to 100.14.23 (really old but it still works with RHEL5/CENTOS5 kernels). I couldn't duplicate this issue in pymol or vmd, but it looks like it happens in coot as well according to you guys.. So I thought it was a problem with the application (I know you're going to say stereo calls are made the same way), but downgrading the driver fixed it for us, but again I couldn't duplicate it in some visualization programs.
