HI,
I just upgraded to MEP 2018 Prem (all patches, etc.) - curious if others are seeing this: Regardless the 3D-stereo source media (raw, no effects, etc.), when I enable any of the stereo view options (upper left pulldown menu in the viewport window - e.g. anaglyph, S-by-S, etc.), the resulting viewport scene is very washed out/desaturated. Setting back to "Standard 2D" returns to proper/expected scene coloration.
Changes to proxy settings (enable/disable, etc.), didn't make a difference, nor did changes to HW playback settings.
3D anaglyph video exports seem to render properly (didn't test others), so it looks like a viewport/rendering issue.
Same machine w VP-X(9) viewport shows the same 3D-Stereo variations working properly w same settings, so I don't think it's my HW setup.
(Edit to add:) I don't believe you have to even be using 3D-stereo media/content to see the effect. Just load a clip and set viewport to a 3D-stereo setting. A 2D source may not look 'correct' in a 3D view, but will probably show the washed out effect...
thanks in advance,
